A '''H-to-MWSS''' is a [[Spartan]] (using an [[Eater 1]] instead of the [[7×9 eater]]) [[converter]] found by [[Tanner Jacobi]] in October {{year|2015}},<ref name="post23888" /> which converts an input [[Herschel]] to a middleweight spaceship. The key discovery was a very small but slightly [[dirty]] H-to-MWSS conduit, where a Herschel is catalyzed to produce an [[MWSS]] but also leaves behind a [[beehive]]. Prefixing two [[R64]] conduits to this produces a [[composite]] converter that successfully deletes the beehive in advance, using the input Herschel's [[first natural glider]].

The repeat time is 157, but it can be reduced to even 72 using the variant below (or other variants, if not required to be spartan).

It consists of a [[syringe]], [[Lx200]], [[L112]], [[L156]], HLx141B, [[BRx46B]], [[BFx59H]], [[R64]], [[Snark]], [[Eater 1]] and the hive-laying H-to-MWSS converter (with the hive deleted by the glider from the HLx141B which travels through the [[Snark]] and [[Eater 1]]).

The infobox pattern contains initial [[ghost Herschel]]s marking the three Herschel (or [[Herschel great-grandparent]]) locations in the H-to-MWSS conduit. The pattern also includes a common way of reaching the input Herschel by prepending an [[Fx77]], but that additional conduit is not a necessary part of the H-to-MWSS. In the pattern shown in the infobox, a "ghost" [[MWSS]] marks the output location.

There are many other ways to remove the unwanted beehive using a spare glider or additional conduits, but they are generally less compact than this.

The form shown here was found by [[Achim Flammenkamp]] in {{year|1988}}.<ref>{{CiteHickersonOscillators|accessdate=March 14, 2020}}</ref> The [[rotor]] is two copies of the rotor of [[1-2-3-4]], so the [[oscillator]] is sometimes called the '''dual 1-2-3-4'''.

==[[List of common oscillators|Commonness]]==
Achim's p4 is about the twenty-third most [[common]] naturally-occurring oscillator in [[Achim Flammenkamp's census]].<ref>{{citeAchim|accessdate=January 15, 2009}}</ref> On [[Catagolue]], it is the third most common period 4 oscillator, being less common than [[mazing]].<ref name="B3/S23/C1">{{citeCatagolue|page=census/b3s23/C1|title=Census|accessdate=October 27, 2018}}</ref> [[Stator]] variants with one<ref name="post14186" /> and three<ref name="post22085" /> bits added respectively are the fourth and eighth most common period-4 oscillators,<ref name="B3/S23/C1" /> and an [[inflected]] version has also occurred naturally.<ref name="post30445" />

==Synthesis==
An {{gliders|8}} [[synthesis]] of this oscillator was found by [[Jason Summers]] in September {{year|2004}}.<ref>{{CiteSummersPattern|name=jslife|accessdate=January 5, 2020}}</ref> In October {{year|2010}}, Lewis Patterson found a [[predecessor]] of this oscillator that allows a {{gliders|7}} synthesis.<ref name="post3685" /><ref name="post3694" /> This was improved to {{gliders|6|brief}} gliders by [[Chris Cain]] in March 2015.<ref name="post17337" />

Cgoler2:

hi, Moderators. I believe WSL is easy to use than cygwin. And it is more convenient to 'install'.
idk whether some of the lifewiki tutorial is obsolete. but at least it should clarify WSL is better alternative to cygwin (since win10 have occupied more than 50% market share){{unsigned|Dylan Chen}}

: Hello, Dylan Chen! I'm recently reconsidering using apgsearch on my laptop and I'd like to refer to your guidance. Would you spare some time to write a step-by-step walkthrough for setting up WSL and apgsearch on Win10 from scratch? You can create a personal sandbox in your user namespace ("User:Dylan_Chen/Sandbox") and start drafting there; later that piece may be merged into this tutorial. See, maintenance work of tutorials is actually not resricted to moderators!

: By the way, please sign your messages on LifeWiki talks with four tildes at the end. It will automatically become a signature like mine: [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 16:12, 15 May 2021 (UTC)

: Win10 occupying 50% of the market does not mean win7 is obselete especially in a geek community. [[User:Ultimium|Ultimium]] ([[User talk:Ultimium|talk]]) 05:19, 20 May 2021 (UTC)

: Could the section which says which still lifes are counted as discoveries be updated? [[User:Cgoler2|Cgoler2]] ([[User talk:Cgoler2|talk]]) 18:20, 28 May 2021 (UTC)

0E0P metacell

The '''0E0P metacell''' is a [[unit cell]] constructed by [[Adam P. Goucher]] between 2014 and 2018.<ref>{{cite web|url=https://cp4space.wordpress.com/2018/11/12/fully-self-directed-replication/ |title=Fully Self-Directed Replication |publisher=Adam P. Goucher |date=November 12, 2018|accessdate=January 8, 2019}}</ref> Like Goucher's previous [[p1 megacell]], it is capable of simulating any [[rule]] using the [[Moore neighborhood|standard eight cell neighborhood]], including [[non-totalistic rule]]s.

The new feature of the 0E0P metacell, and the one that explains its record-breaking large size, is the fact that a group of these metacells can be placed in an empty Life universe with no background grid of OFF metacells, and the entire universe then simulates the rule for which the 0E0P metacells are programmed, at a larger scale by a factor of 262144 = 2<sup>18</sup>. The acronym "0E0P" was originally short for "[State] Zero Encoded by Zero Population", so the OFF state is simply a metacell-sized region of empty space.

When one of these metacells turns off, it self-destructs completely, and when a metacell birth occurs, it must be constructed from the ground up by one of its neighbors. This allows 0E0P metacell patterns, when viewed from very far away (e.g., at a size where an entire metacell takes up a single pixel in the display), to be indistinguishable from normal patterns that use the same rule -- except that the metacell patterns will run 2^36 times more slowly, and if they're run at a step size lower than 2^36, intermediate states may be visible that will depart from a strict pixel-for-pixel match.

The 0E0P metacell ranked second place in the [[Pattern of the Year]] 2018 competition on the [[ConwayLife.com]] forums, behind [[Sir Robin]].<ref name="post68446" />

==Details==
Each individual metacell behaves as an 8-state, 4-neighborhood BCC-automaton; the metacell receives a glider-based signal (a positive integer between 1 and 7, inclusive) from each of its (up to four) neighbours, and a 0 from any empty spaces if there are fewer than four neighbours. It then computes the quantity 8^3 a + 8^2 b + 8^1 c + d, where (a, b, c, d) are the four input signals, and indexes into a 4096-element lookup table to retrieve a value between 0 and 7 (the new ‘state’ of the metacell). If 0, it immediately self-destructs without constructing any children; if nonzero, it constructs a daughter machine in each vacant space. Finally, it broadcasts the new state as a signal to all four neighbours, before self-destructing. In doing so, the metacell behaves as a single cell in any 8-state 4-neighbor cellular automaton; as every 2-state 9-neighbour cellular automaton can be emulated at half the speed as an 8-state 4-neighbour cellular automaton, this allows the 0E0P metacell to emulate rules other than Life, which also allows it to act as a parity-rule [[replicator]], a [[reflectorless rotating oscillator]] (with some limits), and a [[SMOS]] if programmed correctly.

In a healthy 0E0P metacell pattern, metacells could be thought of as living on a diagonally-oriented checkerboard. They're allowed to be present on the dark squares of the checkerboard '''only''' during even 2^35-tick half-cycles, and on the light squares of the checkerboard only during odd half-cycles. At the beginning of each even half-cycle, or in other words at the beginning of each full metatick, the presence or absence of an 0E0P metacell on a dark square corresponds with the presence or absence of an ON cell in an equivalent Life grid (assuming the metacell is programmed to emulate B3/S23). At other times during the 0E0P's replication cycle, the correspondence with cells on a Life grid won't be as clean, but every 2^36 ticks the 0E0P metapattern will come back into perfect alignment.

Every period-2^36 cycle of an 0E0P metacell consists of two period-2^35 half-cycles. In each half-cycle, all metacells make sure that there are child metacells all around them, on the other checkerboard square color -- either by building them, or by attempting to build them and having the construction recipe cleanly eaten by an eater that's part of an already existing child in that location.

Notice that with the 45-degree checkerboard orientation, each grid location in the emulated Life pattern is only half filled by a 0E0P metacell (if one is present). In other words, the metacells are diamond-shaped, not square; their sides don't line up with the emulated Life grid.

Switching checkerboard colors and expanding to four surrounding metacells twice (for two half-cycles) effectively ensures that all eight metacells surrounding any given ON metacell on the same checkerboard square color are occupied by child metacells. These are all the neighbor locations for that particular metacell. No effect can travel faster than lightspeed in the range-1 Moore-neighborhood rules that the 0E0P metacell can emulate, so at the end of two half-cycles, metacells are present in every location where a metacell could possibly be needed to turn ON in the next metatick.

There's no direct communication between an 0E0P metacell and its nearest possible living neighbor metacells to the north, south, east, and west -- i.e., the nearest same-color squares on the 45-degree-angled checkerboard -- let alone between it and the other possibly-living neighbor cells, two checkerboard squares away diagonally. However, by the end of each full cycle, communication between parent and child metacells during each half-cycle has effectively transmitted neighbor state information from one dark-square metacell to all its dark-square neighbors. This means that at the end of each half-cycle, every "potentially alive" 0E0P metacell has all the information it needs to decide whether it should transition to a "fully alive" state and start building child metacells, or if it should immediately self-destruct instead.

==LifeViewer demo==
To demonstrate the full 0E0P metacell cycle and the early self-destruct option, the [[LifeViewer]] demo below shows how a glider made of metacells proceeds through a full 2^36 period (or "metatick"). Note that the gap between metacells where the equivalent cells would be diagonally adjacent will not be visible at the proper zoom level.

==Complexity==
The metacell's circuitry is sufficiently complex that a single Conway's Life meta-[[glider]] requires a compressed pattern file several megabytes in size.<ref name="post65737" /> It can be run in Golly at small step sizes with no difficulty, but simulating an entire replication cycle (half a metatick) is very difficult. On current computers it might take about half a CPU-year using Golly's standard HashLife algorithm.

An order of magnitude improvement over [[HashLife]] is available via Goucher's special-purpose [[StreamLife]] algorithm. However, even using StreamLife it might take several months to simulate the eight replication cycles (four full metaticks) needed to return a metaglider to its original phase. The original experimental verification of a single metatick (12:05 to 12:35 in Cabaret's video below), using rule where a single ON cell is a still life, took about a month.

Signatures are the population counts for the oscillator, sequenced so that the lowest numbers appear to the left. The first signature number has three digits to facilitate sorting when a table includes larger oscillators. Signature numbers are used to break ties in oscillators of nearly the same size.

'''Catagolue'''{{refn|group=note|The name "Catagolue" is an amalgam of "Catalogue" and "GoL" ([[Conway's Game of Life|Game of Life]]).}} is an ongoing distributed [[census]] of naturally occurring [[ash]] objects conducted by [[Adam P. Goucher]], started in late February 2015. The census is primarily focused on asymmetric soups in [[Conway's Game of Life|Conway's Life]], but supports arbitrary [[Life-like cellular automaton|outer-totalistic]] and [[Non-totalistic Life-like cellular automaton|non-totalistic]] rules and a variety of [[symmetry|symmetries]].{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry></nowiki></tt>}} Over 100 users have contributed to the census.

The results are obtained by evolving random [[soup]]s of size 16×16 with [[density]] 0.5 in an infinite planar [[universe]]; as of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types. Submissions of new results (called "hauls") are subjected to both statistical tests and peer-review by other participants before being committed to the census.

Catagolue is primarily fed by [[apgsearch]] 5.x (apgluxe). Each resulting object is identified by [[apgsearch]] by its unique [[apgcode]]; the Catagolue website gives overviews over the various classes of objects found, and provides further information as well as sample soups for each object.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/object/<apgcode>/<rule></nowiki></tt>}} A simple text-based interface for querying sample soups, including their owners, also exists.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/attribute/<apgcode>/<rule>/<symmetry></nowiki></tt>}}

==History==
{{Main|History of Catagolue}}
Catagolue became operative on February 20, 2015.<ref name="calcyman20150220" /> The B3/S23/C1 census reached a total of one trillion objects on April 24, 2015,<ref name="billabob20150424" /> ten trillion objects on September 2, 2015,<ref name="calcyman20150902" /> 100 trillion objects on June 20, 2016,<ref name="applebottom20160620" /> and 200 trillion objects on May 16, 2017.

==Results in Conway's Game of Life==
{{Alsosee|apgsearch#Notable patterns}}

===Asymmetric soups===
{{Alsosee|Most common objects on Catagolue}}
The default rule/symmetry combination for apgsearch, [[Conway's Game of Life|B3/S23]]/C1, is by far the most popular census on Catagolue. As of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types.<ref name="stats" />

==Other rules==
{{Main|List of rules investigated on Catagolue}}
Catagolue also collects census data on various rules other than Conway's Game of Life. In practice, only non-exploding rules can reasonably be investigated unless a certain symmetry can be assured to never explode.

As of January 15, 2019, Catagolue officially supports the following types of cellular automata:
*Arbitrary [[Life-like cellular automaton|outer-totalistic]] rules.
*[[Isotropic non-totalistic Life-like cellular automaton|Isotropic non-totalistic]] rules. (in [[Hensel notation]])
*[[Isotropic]] [[von Neumann neighbourhood]] rules. (implicitly by isotropic non-totalistic [[Moore neighbourhood]] rules)
*Higher-range outer totalistic (HROT) rules. (up to range 5)
*[[Larger than Life]] rules. (up to range 7)
*Totalistic and isotropic [[hexagonal neighbourhood]] rules.
*[[Generations]] variants of all rules listed above.
*[[Life-like cellular automaton|Outer-totalistic]] [[rulespace|B0 rules]] with two states.
*[[BSFKL]] rules.
*[[Deficient]] rules.
*[[Extended Generations]] rules.
*Custom [[Golly]] ruletables.

{{:Catagolue/Stats|numrules}} rules have been investigated at as of {{:Catagolue/Stats|date}}, including the following close Life variants:

* B3/S238 ([[EightLife]])
* B36/S23 ([[HighLife]])
* B368/S238 ([[LowDeath]])
* B38/S23 ([[Pedestrian Life]])
* B38/S238 ([[HoneyLife]])
* B3/S2-i34q ([[tlife]])
* B36/S2-i34q ([[thighlife]])
* B37/S2-i34q ([[tdrylife]])
* B38/S2-i34q ([[tpedestrianlife]])

Other notable rules investigated include:

* B3/S12 ([[Flock]])
* B3/S13 ([[LowLife]])
* B345/S5 ([[Long Life]])
* B36/S125 ([[2×2]])
* B3678/S34678 ([[Day & Night]])
* B368/S245 ([[Move]], aka [[Morley]])
* B2-a/S12 ([[Just Friends]])
* B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e ([[Snowflakes]])
* R5,C0,M1,S34..58,B34..45,NM ([[Bugs]])

A cached list of all rule-symmetry combinations investigated, sorted by last update, is also available.<ref name="post95134" />{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/abclist</nowiki></tt>}}

==Haul verification==
Hauls for official censuses of [[Life-like cellular automaton|Life-like]] rules with at least one trillion objects are subject to statistical verification and peer review before being committed in order to avoid false data being added to the census. As of April 2, 2019, this includes all official apgsearch-supported CPU symmetries for [[Conway's Game of Life]] as well as B38/S23/C1 ([[Pedestrian Life]]), B3/S01367/C1, B35/S136/C1, B3/S12/C1 ([[Flock]]), B3/S2/C1, and B3/S01357/C1.

==Catagolue as a generic pattern inventory==
Although primarily used for soup-searching in practice, Catagolue can be used as a generic pattern inventory/warehouse, as shown by e.g. the slow salvo data it collected (see above). Users are encouraged come up with their own rulestrings, symmetry types, and object codes:

:''[Catagolue] basically accepts anything that you choose to pass off as a rule name, symmetry type, and apgcode. If you make a search program which produces haul files for your favourite CA, then Catagolue will happily build a distributed census [...]''

:''The search program needn't even be a soup search: if you have a depth-first search program such as gfind or zfind, and you have a correspondence between positions in the search tree and alphanumeric strings (where prefixes correspond to ancestors), then you can conduct a distributed search for (say) width-20 c/6 spaceships using the existing Catagolue framework. If you incorporate all of zfind's command-line hyperparameters (period, offset, memory size, etc.) into the beginning of this string, then you can simply have a 'symmetry' called zfind whose tabulations will include things such as xq7, xq10, xq19 (potentially!), etc. And this will work without changing Catagolue in any way.''

::— [[Adam P. Goucher]]<ref name="post48707" />

This is simplified by the <tt>stdin</tt> symmetries of [[apgsearch]], which accept RLEs from standard input to be used in lieu of random soups. [[Arie Paap]] found a c/4 diagonal [[tubstretcher]] in this manner by piping the output of [[ikpx]] into apgsearch.<ref name="post70977" /> This was notable in that the tubstretcher could neither be found by ikpx (which can only find spaceships) nor apgsearch (searching random soups) in isolation.

===Glider syntheses===
{{alsosee|Tutorials/Glider syntheses#Submitting syntheses to Catagolue}}
Catagolue also contains a database of cheapest known [[glider syntheses]] of various objects (including pseudo-objects) retrieved from both [[Shinjuku]] and [[LifeWiki]], and displays them on the respective object page. A list of objects for which syntheses are available is compiled in the <tt>synthesis-costs</tt> [https://catagolue.hatsya.com/census/b3s23/synthesis-costs symmetry] of B3/S23.<ref name="post74801" />

The [https://catagolue.hatsya.com/syntheses "Syntheses" page] of Catagolue transcludes the <tt>synthesis-costs</tt> census and also includes a text box in which users can submit synthesis components in [[RLE]] form to be added to Catagolue's <tt>readsynth</tt> queue.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/readsynth</nowiki></tt>}} These RLE files are automatically parsed and interpreted by Catagolue's thrice-daily update process, and added to the site if they contain new or improved syntheses.{{refn|group=note|As of August 2020, the synthesis submission box does not allow for [[linear growth]] syntheses to be submitted.<ref name="post81683" /> Instead, these must either be added directly to the Catagolue database or added via editing <tt>diffupdate.py</tt>.<ref name="post101839" />}}

==Contributor engagement==
Contributors to Catagolue have user pages tracking their contributions to the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/user/<user name></nowiki></tt>}} In addition to providing an overview of number of objects submitted recently compared to other users, user pages list important discoveries and awarded badges.

Users are credited for discoveries if they find one of the first 20 occurrences of an interesting object: any [[spaceship]] (other than the [[glider]]), any [[oscillator]], any [[Infinite growth#Linear|linear growth]] pattern, or any sufficiently large (≥[[:Category:Strict still lifes with 30 cells|30-bit]]) [[still life]].

The following badges are currently awarded for contributions to B3/S23/C1:

* [[File:Conchita.png]] Conchita{{refn|group=note|The "Conchita" badge is named after [https://en.wikipedia.org/wiki/Conchita_Wurst Conchita Wurst], the Austrian singer who won the 2014 Eurovision Song Contest with the song "Rise Like a Phoenix".}}: find a soup containing a [[phoenix 1|phoenix]].
* [[File:GeminiTheBadge.png]] Gemini: discover a new [[twin bees shuttle]] variant.
* [[File:Gigamyriad.png]] Gigamyriad: contribute 10<sup>13</sup> objects.

* [[File:Trillionaire.png]] Trillionaire: contribute one trillion objects.
* [[File:Voyager.png]] Voyager: find one of the first twenty occurrences of a [[spaceship]].

Interesting new objects are additionally announced on Twitter by an unofficial Twitter bot.

==Backups==
Catagolue census data for the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1, is backed up remotely every day at 17:29;{{refn|group=note|Ramanujan time, after the [https://en.wikipedia.org/wiki/1729_(number) Hardy–Ramanujan number (1729)] of G. H. Hardy's and Srinivasa Ramanujan's.}} the first such backup was made on September 24, 2015. For other symmetries or rules, a remote backup may be instigated manually by calling the <tt>backupcron</tt> endpoint,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/backupcron/<rule>/<symmetry></nowiki></tt>}} with the desired rule and symmetry. Remote backups can be viewed by appending the date (in [https://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format) to the main census URL.{{refn|group=endpoint|name=backup|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry>-<year>-<month>-<day></nowiki></tt>}}

Backups of the <tt>synthesis-costs</tt> census are automatically made three times a month, specifically on dates ending with a "5", and can be accessed using the <tt>year-month-day</tt> method.{{refn|group=endpoint|name=backup}}

Local backups of Catagolue census data may be made by calling the <tt>textcensus</tt> endpoint for the desired rule and symmetry.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry></nowiki></tt>}} The list of objects returned can be sorted by object frequency,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/sorted</nowiki></tt>}} but this should be avoided when possible to reduce server load.<ref name="calcyman20170129" /> It is also possible to restrict objects returned to a certain prefix,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/<prefix></nowiki></tt>}} or to query the number of objects, grouped by prefix and including a total.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/objcount</nowiki></tt>}}

==Limitations==
{{alsosee|apgsearch#Limitations}}

===Server===
Catagolue does not accept hauls exceeding 1 MiB; additionally, hauls must contains a minimum of 10,000 soups or 250,000 objects.<ref name="calcyman20160630" />

Each tabulation on Catagolue also has a maximum size of 1 MB imposed by Google Cloud Datastore; obscure objects will sometimes be deleted from these tabulations to meet this limit.<ref name="post64739" /> In December 2018, Catagolue switched to a new compression system, allowing certain [[:Category:Oscillators with period 2|period 2]] [[oscillator]]s to be manually readded to the D8_1 and D8_4 censuses without meeting the 1 MB limit.<ref name="post66653" />

===Web frontend===
Although Catagolue verifies that an object in a given rule behaves as specified by its code, the site makes no attempt to reject non-canonical codes (e.g. <tt>xp2_222</tt> rather than <tt>xp2_7</tt> for the [[blinker]]); furthermore, the site accepts various anomalous prefixes (e.g. <tt>xp0</tt> and <tt>xq0</tt>). No attempt is made to normalize or reject anomalous rules (e.g. "<tt>b33s23</tt>"), although a feature is planned to clear out censuses which do not adhere to the [[Catagolue naming conventions]].

Catagolue's <tt>hashsoup</tt> functionality, used for retrieving sample soups from the database,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/hashsoup/<symmetry>/<id>/<rule></nowiki></tt>}} only recognizes official square grid symmetries and D2_xo,{{refn|group=note|D2_xo is simply an orthogonal reflection of the equivalent D2_x soup for the [[Moore neighbourhood]], but functions as a distinct symmetry in hexagonal rules.}} and defaults to C1 for all others. Soups with symmetries exclusive to the [[hexagonal neighbourhood|hexagonal grid]] (i.e. containing <tt>C3</tt>, <tt>C6</tt>, <tt>D6</tt>, or <tt>D12</tt>) must instead be reconstructed using [[lifelib]].<ref name="post66638" />

The '''lightweight spaceship''' (commonly abbreviated to '''LWSS''') or (rarely) '''small fish'''<ref>{{CiteLexicon|file=lex_s.htm#smallfish|name=Small fish|accessdate=June 10, 2009}}</ref> is the smallest orthogonal [[spaceship]], and the second most common spaceship after the [[glider]]. It moves at speed [[c/2 orthogonal|c/2]] and has [[period]] {{periodS|4|brief}} (and is therefore often referred to as 2c/4). It was found by [[John Conway]] in {{year|1970}}.

==[[List of common spaceships|Commonness]]==
Random soups investigated by Achim Flammenkamp emitted one LWSS for approximately every 615 gliders.<ref>{{cite web|url=http://wwwhomes.uni-bielefeld.de/achim/moving.html |title=Spontaneous appeared Spaceships out of Random Dust |publisher=Achim Flammenkamp |date=December 9, 1995|accessdate=August 18, 2011}}</ref> The LWSS is also the eighteenth most common object on [[Adam P. Goucher]]'s [[Catagolue]].<ref>{{citeCatagolueStats|June 24, 2016}}</ref>

==Tagalong==
In April {{year|1992}}, [[David Bell]] found a [[tagalong]] for two lightweight spaceships (or two [[middleweight spaceship]]s or two [[heavyweight spaceship]]s). It can be extended indefinitely by attaching it to the back of itself. Interestingly, a [[hivenudger]] with symmetric rear (that is, both rear spaceships being of same "weight") can pull this tagalong.

{{disambiglink|name=glider|text=For other meanings of the term}}
The '''glider''' (or '''featherweight spaceship'''<ref>{{CiteLexicon|file=lex_f.htm#featherweightspaceship|name=Featherweight spaceship|accessdate=December 3, 2018}}</ref>) is the smallest, most common, and first-discovered [[spaceship]]. It travels diagonally across the [[Life]] grid at a speed of [[c/4 diagonal|c/4]]. Gliders are important because they are easily produced (for an example see the [[Gosper glider gun]]), can be collided with each other to form more complicated objects (see [[glider synthesis]]), and can be used to transmit information over long distances.

Its name is due in part to the fact that it is [[glide symmetric]]; however, John Conway has stated he regrets calling it a glider, saying it looks more like an ant walking across the plane.<ref>{{cite web|url=https://www.youtube.com/watch?v=E8kUJL04ELA&t=3m55s|title=Does John Conway hate using Game of Life?|publisher=Numberphile|date=3 Mar 2014|accessdate=13 Jun 2016}}</ref>

==Discovery==
The glider was found by [[Richard K. Guy]] in {{year|1969}} while Conway's group was attempting to track the evolution of the [[R-pentomino]]. It is often wrongly stated that [[John Conway]] discovered the glider, but Conway himself has said that it was Guy, a fact expounded in Conway's biography, ''[[Genius at Play]]'':<ref name="geniusatplay125" />

{{Cquote|{{...}} They'd all head back to the department eventually and continue on the trail of the methuselah r-pentomino, hoping to happen upon an information stream. The Life computer program was still in the works, so frustration over their lack of success was exacerbated by the fact that the investigators were still working manually. Even 10 generations proved nearly impossible to document accurately without elaborate and diligent checks. In this regard, a force for good arrived in the form of Richard Guy, Mike's father, who visited nearly every summer. British-born, he had studied mathematics at Cambridge, spending much of his time playing and analyzing chess, composing endgame problems that he published in the ''British Chess Magazine''. This led to his intensive games research, considered pivotal in the history of combinatorial game theory. He served in the Royal Air Force during the war and as a meteorologist in Iceland and Bermuda, then lectured for a time at the University of London, as well as in Singapore and in Delhi at the Indian Institute of Technology, before eventually landing at the University of Calgary. A precisian fellow—precise, careful, fastidious, conscientious—qualities of character that the Lifers on the whole lacked. Conway appointed him “blinker watcher,” a tedious task. He kept an accounting of blinkers and other debris that splintered off from center stage as the action in the spotlight evolved generation upon generation.

Late in the fall of 1969, as the group was still on the trail of the r-pentomino, the elder Guy's attention to detail paid off. The drama had been building since generation 27, when the scene split, stage left and stage right, each a microcosm of chaos unto itself. At generation 69, Guy noticed an animal that no one had ever seen before. It seemed to be wiggling, skittering, gliding its way diagonally across the board. He hollered to the others: “Come over here, there's a piece that's walking!” This was the first step toward proving Life universal. Conway christened this walking piece the “glider” (though now he wishes he'd called it the “ant”), because after two moves its position differs from the starting position by a “glide reflection,” a symmetry operation, and at generation 4 it looks exactly the same as it did at generation 0, but it has glided diagonally downward by a single place. {{...}}}}

'''Historical note:''' An R-pentomino tracked past T=69 in late 1969 certainly implies that the glider, and a number of other objects such as [[block]]s and [[blinker]]s, were first seen by Conway's group before 1970. However, for most objects it is difficult to pinpoint a definite date of discovery, so the LifeWiki and other sources traditionally use 1970 as the official figure for any objects known at the time of publication of Martin Gardner's first Scientific American article in October 1970. For many years Conway consistently "rounded up" his discovery of the Game of Life to 1970.

==[[List of common spaceships|Commonness]]==
The glider is often produced by randomly-generated starting [[pattern]]s;<ref>{{cite web|url=http://wwwhomes.uni-bielefeld.de/achim/moving.html |title=Spontaneous appeared Spaceships out of Random Dust |publisher=Achim Flammenkamp |date=December 9, 1995|accessdate=February 27, 2009}}</ref> it is the fourth most common object on [[Adam P. Goucher]]'s [[Catagolue]].<ref>{{citeCatagolueStats|June 24, 2016}}</ref>

==Glider synthesis==
{{main|Glider synthesis}}
'''Glider synthesis''' is the construction of an object by means of glider collisions. It is generally assumed that the gliders should be arranged so that they could come from infinity - that is, gliders should not have had to pass through one another to achieve the initial arrangement.<ref>{{CiteLexicon|file=lex_g.htm#glidersynthesis|name=Glider synthesis|accessdate=May 21, 2009}}</ref>

Glider syntheses for all [[still life]]s with at most 18 [[cell]]s<ref>{{cite web|url=http://pentadecathlon.com/lifeNews/2014/05/constructions_known_for_all_st.html |title=Constructions Known for All Still Lifes up to 17 Bits |work=Game of Life News |publisher=Dave Greene |accessdate=September 17, 2014}}</ref><ref>{{cite web|url=http://www.conwaylife.com/forums/viewtopic.php?f=2&t=1467#p13607 |title=18-bit SL Syntheses (100% Complete!)}}</ref> and known [[oscillator]]s with at most 14 cells have been explicitly constructed.

==Colour of a glider==
The '''colour''' of a glider is a property of the glider which remains constant while the glider is moving along a straight path, but which can be changed when the glider bounces off a [[reflector]]. It is an important consideration when building something using reflectors.

To define the colour of a glider, first choose some cell to be the origin. This cell is then considered to be black, and all other cells to be black or white in a checkerboard pattern (i.e. the cell with coordinates (m,n) is black if m+n is even, and white otherwise).

Then the colour of a glider is the colour of its leading cell when it is in the following [[phase]]:

<center>[[File:Glider.png]]</center>

Or the centre (or dot) cell for this phase:

<center>[[Image:Move9.GIF|center|80px]]</center>

This definition is the same for any rotated version of the above phases, but not for mirror-reflected versions. A reflected version has to be advanced by two ticks to bring it back to one of these "canonical" phases, which has the effect of moving the key cells to the opposite color.

A reflector which does not change the colour of gliders obviously can not be used to move a glider onto a path of different colour than it started on. However, a 90-degree reflector which does change the colour of gliders is similarly limited, as the colour of the resulting glider will depend only on the direction of the glider, no matter how many reflectors are used. For maximum flexibility, therefore, both types of reflector are required.<ref>{{CiteLexicon|file=lex_c.htm#colourofaglider|name=Colour of a glider|accessdate=April 22, 2009}}</ref>

An example of a colour-preserving reflector is the [[bumper]].
An example of a colour-changing reflector is the [[bouncer]].

In golly, setting the bold grid lines every 2 cells will help determine the color of a glider. SW and NE are same colour, NW and SE are same colour.

The '''parity''' of a glider is the shape of it. Gliders come in 4 phases of 2 different shapes.
<center>[[Image:Move9.GIF|center|80px]]</center>
<center>[[File:Glider.png]]</center>
It is useful to know the parity for rephasing glider [[stream]]s.

==Architecture==
The computer supports eight variables and 13 instructions -- '''write''', '''goto''', '''move''', '''jumpif''', '''print''', '''add''', '''or''', '''and''', '''xor''', '''not''', '''flat''', '''sign''', and '''increment'''. The computer is programmed by changing the arrangement of structures in its Program area.

==Comparison with other computer patterns==
* The 8-bit programmable computer is considerably simpler than the [[Spartan universal computer-constructor]], in large part because it does not contain a universal-construction component.
* It is easy to program with the help of the associated Python utility script, assembly.py, and associated resources which can be found in the project's GitHub repository.<ref>{{cite web|url=https://github.com/nicolasloizeau/gol-computer|title=GOL computer|author=Nicolas Loizeau|date=18 November 2018|accessdate=30 October 2019}}</ref>
* It is capable of performing standard 8-bit AND, OR, XOR, and NOT operations using any of its eight variables.

'''Sir Robin'''{{refn|group=note|The name is in reference to [https://www.youtube.com/watch?v{{=}}BZwuTo7zKM8 Sir Robin], the knight who "bravely ran away", from Monty Python's movie ''[https://en.wikipedia.org/wiki/Monty_Python_and_the_Holy_Grail Monty Python and the Holy Grail]''.}} is a [[(2,1)c/6]] [[spaceship]] found by [[Adam P. Goucher]] on March 6, {{year|2018}} using his [[ikpx]] search program.

Sir Robin is also known by its systematic name '''282P6H2V1''', and is alternatively called '''seahorse''' or '''Minstrel 0''' / '''M0''' (see [[Sir Robin#Tagalongs|Tagalongs]] below). It is based on a partial found by [[Tomas Rokicki]], which makes up about 62% of the ship,<ref name="thread3303" /> and roughly half of which was itself an independent rediscovery of a partial found by [[Josh Ball]] in April {{year|2017}}.<ref name="post42467" /> Sir Robin is the first [[elementary]] [[knightship]] in [[Conway's Game of Life]], and the only elementary knightship in that rule until the discovery of the [[sprayer]]. A scientific paper describing the method used to find the ship is forthcoming.<ref name="post57456" />

Sir Robin was voted on the [[ConwayLife.com]] forums as [[Pattern of the Year]] 2018.<ref name="post68446" />

==Partials==
Josh Ball's original partial from April 2017 is shown below:

}}

==Synthesis==
No [[glider synthesis]] for Sir Robin exists as of July 2019; finding a synthesis is considered a challenging task at best, due to the large size of the ship, and the amount of [[space dust]] it contains. A fake 87-glider synthesis (actually a clever [[LifeViewer]] loop) was posted by [[Dave Greene]] on April Fools' Day 2018.<ref name="post58732" />

==Reactions==
[[Martin Grant]] constructed a Sir Robin [[eater]] with a [[repeat time]] of 557 on March 8, 2018:<ref name="post57499" />

==Tagalongs==
[[Tagalong]]s of Sir Robin are dubbed '''minstrels'''.{{refn|group=note|"Minstrel", like "Sir Robin", is a reference to Monty Python's movie ''Monty Python and the Holy Grail''.}} There are many ways in which Sir Robin can be extended by attaching minstrels:

The complete spaceships are named '''Minstrel 0''' (Sir Robin) through to '''Minstrel 15''' and '''Minstrel 18''', agreeing with order of discovery up to Minstrel 10 and departing slightly thereafter. The [[elementary]] components are given the following names:

* Sir Robin := Minstrel 0
* Errant minstrel := Minstrel 1 - Minstrel 0
* Lightweight minstrel := Minstrel 2 - Minstrel 0
* Heavyweight minstrel := Minstrel 3 - Minstrel 0
* Wandering minstrel := Minstrel 5 - Minstrel 3
* Ragged minstrel := Minstrel 6 - Minstrel 2
* Featherweight minstrel := Minstrel 9 - Minstrel 6
* Pi minstrel := Minstrel 10 - Minstrel 3
* Connecting minstrel := Minstrel 11 - Minstrel 5
* Fountain minstrel := Minstrel 12 - Minstrel 1

Several of these "elementary minstrels" are not technically true tagalongs, because they slightly modify the trailing sparks on the spaceship to which they attach.

===History===

The first tagalong, '''Minstrel 1''', was discovered by [[Adam P. Goucher]] on July 15, {{year|2018}}, after resuming the original [[ikpx]] search.<ref name="post61918" />

[[Dave Greene]] modified [[Martin Grant]]'s Sir Robin eater to act as a Minstrel 1 detector the same day, which removes the errant minstrel to yield the original Sir Robin.<ref name="post61925" />

On July 19, {{year|2018}}, [[Adam P. Goucher]] found a second and third minstrel, dubbed '''Minstrel 2''' and '''Minstrel 3''', that follow Sir Robin more closely. The lightweight and heavyweight minstrels are not true tagalongs because they change the evolution of the Sir Robin itself.<ref name="post62007" />

On July 20, {{year|2018}}, [[Goldtiger997]] built a [[stable]] circuit that can accept any of Minstrel 0 through to Minstrel 3,<ref name="post62052" /> emitting a glider in one of four directions (depending on the input spaceship) along with an unadorned Sir Robin travelling along the original path. When the original input is a Sir Robin, this circuit is a [[Heisenburp]]; otherwise, it is a [[downconverter]]. The circuit was later optimised by including a bend in the [[2c/3 signal]] wire, among other bounding-box reductions.

On Christmas Day in 2018, [[Entity Valkyrie]] discovered that the heavyweight and errant can be composed, yielding '''Minstrel 4'''<ref name="post66748" />. Two days later, Goldtiger997 updated the previous minstrel remover/detector to accept any of the known tagalongs including the composite Minstrel 4.<ref name="post66802" />

On December 31, 2018, [[Adam P. Goucher]] resumed the [[ikpx]] search and another Minstrel 3 tagalong was found, dubbed Minstrel 5. Again, Goldtiger997's minstrel remover/detector was updated to accept the newest spaceship.

The following month a further tagalong, '''Minstrel 6''', was discovered by the ikpx search program, and was added to existing components to produce two new spaceships, '''Minstrels 7 and 8'''. '''Minstrel 9''' followed shortly after, on the 18th January, and another "pi minstrel" tagalong was discovered on the 21st of January which created '''Minstrels 10 and 13'''. A longer tagalong discovered in early February produced '''Minstrels 11 and 14''' in the same way, and also enabled much simpler [[branching spaceship|branching knightships]]. The following day a tagalong to the errant minstrel was discovered, yielding '''Minstrels 12, 15, and 18'''.

===Minstrel arithmetic===

Due to increasingly large liberties taken with the initial chronological numbering (beginning with the dicovery of minstrel 13), the relationships between these spaceships can be encapsulated by 'minstrel arithmetic': the observation that integer 'weights' can be assigned to Sir Robin and its indecomposable tagalongs such that the sum of the weights of the components of '''Minstrel n''' is exactly n:

* Sir Robin: 0
* Errant minstrel: 1
* Lightweight minstrel: 2
* Heavyweight minstrel: 3
* Wandering minstrel: 2
* Ragged minstrel: 4
* Featherweight minstrel: 3
* Pi minstrel: 7
* Connecting minstrel: 6
* Fountain minstrel: 11

In particular, we have:

* Minstrel 0 = 0 (Sir Robin)
* Minstrel 1 = 0 + 1 (Sir Robin + errant minstrel)
* Minstrel 2 = 0 + 2 (Sir Robin + lightweight minstrel)
* Minstrel 3 = 0 + 3 (Sir Robin + heavyweight minstrel)
* Minstrel 4 = 0 + 3 + 1 (Sir Robin + heavyweight minstrel + errant minstrel)
* Minstrel 5 = 0 + 3 + 2 (Sir Robin + heavyweight minstrel + wandering minstrel)
* Minstrel 6 = 0 + 2 + 4 (Sir Robin + lightweight minstrel + ragged minstrel)
* Minstrel 7 = 0 + 2 + 4 + 1 (Sir Robin + lightweight minstrel + ragged minstrel + errant minstrel)
* Minstrel 8 = 0 + 2 + 4 + 2 (Sir Robin + lightweight minstrel + ragged minstrel + wandering minstrel)
* Minstrel 9 = 0 + 2 + 4 + 3 (Sir Robin + lightweight minstrel + ragged minstrel + featherweight minstrel)
* Minstrel 10 = 0 + 3 + 7 (Sir Robin + heavyweight minstrel + pi minstrel)
* Minstrel 11 = 0 + 3 + 2 + 6 (Sir Robin + heavyweight minstrel + wandering minstrel + connecting minstrel)
* Minstrel 12 = 0 + 1 + 11 (Sir Robin + errant minstrel + fountain minstrel)
* Minstrel 13 = 0 + 2 + 4 + 7 (Sir Robin + lightweight minstrel + ragged minstrel + pi minstrel)
* Minstrel 14 = 0 + 2 + 4 + 2 + 6 (Sir Robin + lightweight minstrel + ragged minstrel + wandering minstrel + connecting minstrel)
* Minstrel 15 = 0 + 3 + 1 + 11 (Sir Robin + heavyweight minstrel + errant minstrel + fountain minstrel)
* Minstrel 18 = 0 + 2 + 4 + 1 + 11 (Sir Robin + lightweight minstrel + ragged minstrel + errant minstrel + fountain minstrel)

==Other spaceships==

The lightweight minstrel is also capable of supporting both ends of [[knightwave]], as noted by Matthias Merzenich. The heavyweight minstrel can support the left end in the same manner.<ref name="post57379" />

If direct connections to the left and right sides of Sir Robin spaceships are included, (2,1)c/6 technology now allows [[branching spaceship]]s, since it is possible to make connections in three directions from a single spaceship. The known direct connection between two Sir Robin spaceships makes a slightly steeper angle than a knightwave -- (15, -13) instead of (5, -3). This means that any added branch on the left side (as in the example shown above) runs out of space after six direct connections have been made. However, direct-connection branches on the right eventually allow additional three-way branch points to be connected.<ref name="post69094" /> The "connecting minstrel" enables another type of branching-spaceship connection with much more clearance.<ref name="post69314" />

Thus, until the discovery of the [[sprayer]], every known (2,1)c/6 spaceship was either:

* Minstrel n (for some n between 0 and 15, as well as 18), or
* A sequence of two or more spaceships, each of the above form, with adjacent spaceships joined by one of three types of connections:
# a horizontal segment of [[knightwave]] containing any sufficiently large number of repeating components (where 'sufficiently large' is such that the two knightships do not interact, i.e. 3 units), or
# a direct diagonal connection between two Sir Robin spaceships, changing the position of one cell along the connected edge for a single tick (compare the right edges of the two directly connected Sir Robins at T=0 in the example above), or
# a connection between the tail of '''Minstrel 14''' and the direct-connection point on any '''Minstrel 0 to 15''' (or '''18'''), or
* a branching spaceship consisting of multiple connected sequences as described above.

The leftmost spaceship in a knightwave sequence must contain either a lightweight or heavyweight minstrel, and the remaining spaceships must all contain lightweight minstrels.

'''Sir Robin'''{{refn|group=note|The name is in reference to [https://www.youtube.com/watch?v{{=}}BZwuTo7zKM8 Sir Robin], the knight who "bravely ran away", from Monty Python's movie ''[https://en.wikipedia.org/wiki/Monty_Python_and_the_Holy_Grail Monty Python and the Holy Grail]''.}} is a [[(2,1)c/6]] [[spaceship]] found by [[Adam P. Goucher]] on March 6, {{year|2018}} using his [[ikpx]] search program.

Sir Robin is also known by its systematic name '''282P6H2V1''', and is alternatively called '''seahorse''' or '''Minstrel 0''' / '''M0''' (see [[Sir Robin#Tagalongs|Tagalongs]] below). It is based on a partial found by [[Tomas Rokicki]], which makes up about 62% of the ship,<ref name="thread3303" /> and roughly half of which was itself an independent rediscovery of a partial found by [[Josh Ball]] in April {{year|2017}}.<ref name="post42467" /> Sir Robin is the first [[elementary]] [[knightship]] in [[Conway's Game of Life]], and the only elementary knightship in that rule until the discovery of the [[sprayer]]. A scientific paper describing the method used to find the ship is forthcoming.<ref name="post57456" />

Sir Robin was voted on the [[ConwayLife.com]] forums as [[Pattern of the Year]] 2018.<ref name="post68446" />

==Partials==
Josh Ball's original partial from April 2017 is shown below:

|viewerconfig = #C [[ ZOOM 16 THUMBSIZE 2 WIDTH 640 HEIGHT 560 GPS 6 ]]
}}

==Synthesis==
No [[glider synthesis]] for Sir Robin exists as of July 2019; finding a synthesis is considered a challenging task at best, due to the large size of the ship, and the amount of [[space dust]] it contains. A fake 87-glider synthesis (actually a clever [[LifeViewer]] loop) was posted by [[Dave Greene]] on April Fools' Day 2018.<ref name="post58732" />

==Reactions==
[[Martin Grant]] constructed a Sir Robin [[eater]] with a [[repeat time]] of 557 on March 8, 2018:<ref name="post57499" />

==Tagalongs==
[[Tagalong]]s of Sir Robin are dubbed '''minstrels'''.{{refn|group=note|"Minstrel", like "Sir Robin", is a reference to Monty Python's movie ''Monty Python and the Holy Grail''.}} There are many ways in which Sir Robin can be extended by attaching minstrels:

The complete spaceships are named '''Minstrel 0''' (Sir Robin) through to '''Minstrel 15''' and '''Minstrel 18''', agreeing with order of discovery up to Minstrel 10 and departing slightly thereafter. The [[elementary]] components are given the following names:

* Sir Robin := Minstrel 0
* Errant minstrel := Minstrel 1 - Minstrel 0
* Lightweight minstrel := Minstrel 2 - Minstrel 0
* Heavyweight minstrel := Minstrel 3 - Minstrel 0
* Wandering minstrel := Minstrel 5 - Minstrel 3
* Ragged minstrel := Minstrel 6 - Minstrel 2
* Featherweight minstrel := Minstrel 9 - Minstrel 6
* Pi minstrel := Minstrel 10 - Minstrel 3
* Connecting minstrel := Minstrel 11 - Minstrel 5
* Fountain minstrel := Minstrel 12 - Minstrel 1

Several of these "elementary minstrels" are not technically true tagalongs, because they slightly modify the trailing sparks on the spaceship to which they attach.

===History===

The first tagalong, '''Minstrel 1''', was discovered by [[Adam P. Goucher]] on July 15, {{year|2018}}, after resuming the original [[ikpx]] search.<ref name="post61918" />

[[Dave Greene]] modified [[Martin Grant]]'s Sir Robin eater to act as a Minstrel 1 detector the same day, which removes the errant minstrel to yield the original Sir Robin.<ref name="post61925" />

On July 19, {{year|2018}}, [[Adam P. Goucher]] found a second and third minstrel, dubbed '''Minstrel 2''' and '''Minstrel 3''', that follow Sir Robin more closely. The lightweight and heavyweight minstrels are not true tagalongs because they change the evolution of the Sir Robin itself.<ref name="post62007" />

On July 20, {{year|2018}}, [[Goldtiger997]] built a [[stable]] circuit that can accept any of Minstrel 0 through to Minstrel 3,<ref name="post62052" /> emitting a glider in one of four directions (depending on the input spaceship) along with an unadorned Sir Robin travelling along the original path. When the original input is a Sir Robin, this circuit is a [[Heisenburp]]; otherwise, it is a [[downconverter]]. The circuit was later optimised by including a bend in the [[2c/3 signal]] wire, among other bounding-box reductions.

On Christmas Day in 2018, [[Entity Valkyrie]] discovered that the heavyweight and errant can be composed, yielding '''Minstrel 4'''<ref name="post66748" />. Two days later, Goldtiger997 updated the previous minstrel remover/detector to accept any of the known tagalongs including the composite Minstrel 4.<ref name="post66802" />

On December 31, 2018, [[Adam P. Goucher]] resumed the [[ikpx]] search and another Minstrel 3 tagalong was found, dubbed Minstrel 5. Again, Goldtiger997's minstrel remover/detector was updated to accept the newest spaceship.

The following month a further tagalong, '''Minstrel 6''', was discovered by the ikpx search program, and was added to existing components to produce two new spaceships, '''Minstrels 7 and 8'''. '''Minstrel 9''' followed shortly after, on the 18th January, and another "pi minstrel" tagalong was discovered on the 21st of January which created '''Minstrels 10 and 13'''. A longer tagalong discovered in early February produced '''Minstrels 11 and 14''' in the same way, and also enabled much simpler [[branching spaceship|branching knightships]]. The following day a tagalong to the errant minstrel was discovered, yielding '''Minstrels 12, 15, and 18'''.

===Minstrel arithmetic===

Due to increasingly large liberties taken with the initial chronological numbering (beginning with the dicovery of minstrel 13), the relationships between these spaceships can be encapsulated by 'minstrel arithmetic': the observation that integer 'weights' can be assigned to Sir Robin and its indecomposable tagalongs such that the sum of the weights of the components of '''Minstrel n''' is exactly n:

* Sir Robin: 0
* Errant minstrel: 1
* Lightweight minstrel: 2
* Heavyweight minstrel: 3
* Wandering minstrel: 2
* Ragged minstrel: 4
* Featherweight minstrel: 3
* Pi minstrel: 7
* Connecting minstrel: 6
* Fountain minstrel: 11

In particular, we have:

* Minstrel 0 = 0 (Sir Robin)
* Minstrel 1 = 0 + 1 (Sir Robin + errant minstrel)
* Minstrel 2 = 0 + 2 (Sir Robin + lightweight minstrel)
* Minstrel 3 = 0 + 3 (Sir Robin + heavyweight minstrel)
* Minstrel 4 = 0 + 3 + 1 (Sir Robin + heavyweight minstrel + errant minstrel)
* Minstrel 5 = 0 + 3 + 2 (Sir Robin + heavyweight minstrel + wandering minstrel)
* Minstrel 6 = 0 + 2 + 4 (Sir Robin + lightweight minstrel + ragged minstrel)
* Minstrel 7 = 0 + 2 + 4 + 1 (Sir Robin + lightweight minstrel + ragged minstrel + errant minstrel)
* Minstrel 8 = 0 + 2 + 4 + 2 (Sir Robin + lightweight minstrel + ragged minstrel + wandering minstrel)
* Minstrel 9 = 0 + 2 + 4 + 3 (Sir Robin + lightweight minstrel + ragged minstrel + featherweight minstrel)
* Minstrel 10 = 0 + 3 + 7 (Sir Robin + heavyweight minstrel + pi minstrel)
* Minstrel 11 = 0 + 3 + 2 + 6 (Sir Robin + heavyweight minstrel + wandering minstrel + connecting minstrel)
* Minstrel 12 = 0 + 1 + 11 (Sir Robin + errant minstrel + fountain minstrel)
* Minstrel 13 = 0 + 2 + 4 + 7 (Sir Robin + lightweight minstrel + ragged minstrel + pi minstrel)
* Minstrel 14 = 0 + 2 + 4 + 2 + 6 (Sir Robin + lightweight minstrel + ragged minstrel + wandering minstrel + connecting minstrel)
* Minstrel 15 = 0 + 3 + 1 + 11 (Sir Robin + heavyweight minstrel + errant minstrel + fountain minstrel)
* Minstrel 18 = 0 + 2 + 4 + 1 + 11 (Sir Robin + lightweight minstrel + ragged minstrel + errant minstrel + fountain minstrel)

==Other spaceships==

The lightweight minstrel is also capable of supporting both ends of [[knightwave]], as noted by Matthias Merzenich. The heavyweight minstrel can support the left end in the same manner.<ref name="post57379" />

If direct connections to the left and right sides of Sir Robin spaceships are included, (2,1)c/6 technology now allows [[branching spaceship]]s, since it is possible to make connections in three directions from a single spaceship. The known direct connection between two Sir Robin spaceships makes a slightly steeper angle than a knightwave -- (15, -13) instead of (5, -3). This means that any added branch on the left side (as in the example shown above) runs out of space after six direct connections have been made. However, direct-connection branches on the right eventually allow additional three-way branch points to be connected.<ref name="post69094" /> The "connecting minstrel" enables another type of branching-spaceship connection with much more clearance.<ref name="post69314" />

Thus, until the discovery of the [[sprayer]], every known (2,1)c/6 spaceship was either:

* Minstrel n (for some n between 0 and 15, as well as 18), or
* A sequence of two or more spaceships, each of the above form, with adjacent spaceships joined by one of three types of connections:
# a horizontal segment of [[knightwave]] containing any sufficiently large number of repeating components (where 'sufficiently large' is such that the two knightships do not interact, i.e. 3 units), or
# a direct diagonal connection between two Sir Robin spaceships, changing the position of one cell along the connected edge for a single tick (compare the right edges of the two directly connected Sir Robins at T=0 in the example above), or
# a connection between the tail of '''Minstrel 14''' and the direct-connection point on any '''Minstrel 0 to 15''' (or '''18'''), or
* a branching spaceship consisting of multiple connected sequences as described above.

The leftmost spaceship in a knightwave sequence must contain either a lightweight or heavyweight minstrel, and the remaining spaceships must all contain lightweight minstrels.

'''Catagolue'''{{refn|group=note|The name "Catagolue" is an amalgam of "Catalogue" and "GoL" ([[Conway's Game of Life|Game of Life]]).}} is an ongoing distributed [[census]] of naturally occurring [[ash]] objects conducted by [[Adam P. Goucher]], started in late February 2015. The census is primarily focused on asymmetric soups in [[Conway's Game of Life|Conway's Life]], but supports arbitrary [[Life-like cellular automaton|outer-totalistic]] and [[Non-totalistic Life-like cellular automaton|non-totalistic]] rules and a variety of [[symmetry|symmetries]].{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry></nowiki></tt>}} Over 100 users have contributed to the census.

The results are obtained by evolving random [[soup]]s of size 16×16 with [[density]] 0.5 in an infinite planar [[universe]]; as of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types. Submissions of new results (called "hauls") are subjected to both statistical tests and peer-review by other participants before being committed to the census.

Catagolue is primarily fed by [[apgsearch]] 5.x (apgluxe). Each resulting object is identified by [[apgsearch]] by its unique [[apgcode]]; the Catagolue website gives overviews over the various classes of objects found, and provides further information as well as sample soups for each object.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/object/<apgcode>/<rule></nowiki></tt>}} A simple text-based interface for querying sample soups, including their owners, also exists.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/attribute/<apgcode>/<rule>/<symmetry></nowiki></tt>}}

==History==
{{Main|History of Catagolue}}
Catagolue became operative on February 20, 2015.<ref name="calcyman20150220" /> The B3/S23/C1 census reached a total of one trillion objects on April 24, 2015,<ref name="billabob20150424" /> ten trillion objects on September 2, 2015,<ref name="calcyman20150902" /> 100 trillion objects on June 20, 2016,<ref name="applebottom20160620" /> and 200 trillion objects on May 16, 2017.

===Asymmetric soups===
{{Alsosee|Most common objects on Catagoluge}}
The default rule/symmetry combination for apgsearch, [[Conway's Game of Life|B3/S23]]/C1, is by far the most popular census on Catagolue. As of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types.<ref name="stats" />

==Other rules==
{{Main|List of rules investigated on Catagolue}}
Catagolue also collects census data on various rules other than Conway's Game of Life. In practice, only non-exploding rules can reasonably be investigated unless a certain symmetry can be assured to never explode.

As of January 15, 2019, Catagolue officially supports the following types of cellular automata:
*Arbitrary [[Life-like cellular automaton|outer-totalistic]] rules.
*[[Isotropic non-totalistic Life-like cellular automaton|Isotropic non-totalistic]] rules. (in [[Hensel notation]])
*[[Isotropic]] [[von Neumann neighbourhood]] rules. (implicitly by isotropic non-totalistic [[Moore neighbourhood]] rules)
*Higher-range outer totalistic (HROT) rules. (up to range 5)
*[[Larger than Life]] rules. (up to range 7)
*Totalistic and isotropic [[hexagonal neighbourhood]] rules.
*[[Generations]] variants of all rules listed above.
*[[Life-like cellular automaton|Outer-totalistic]] [[rulespace|B0 rules]] with two states.
*[[BSFKL]] rules.
*[[Deficient]] rules.
*[[Extended Generations]] rules.
*Custom [[Golly]] ruletables.

{{:Catagolue/Stats|numrules}} rules have been investigated at as of {{:Catagolue/Stats|date}}, including the following close Life variants:

* B3/S238 ([[EightLife]])
* B36/S23 ([[HighLife]])
* B368/S238 ([[LowDeath]])
* B38/S23 ([[Pedestrian Life]])
* B38/S238 ([[HoneyLife]])
* B3/S2-i34q ([[tlife]])
* B36/S2-i34q ([[thighlife]])
* B37/S2-i34q ([[tdrylife]])
* B38/S2-i34q ([[tpedestrianlife]])

Other notable rules investigated include:

* B3/S12 ([[Flock]])
* B3/S13 ([[LowLife]])
* B345/S5 ([[Long Life]])
* B36/S125 ([[2×2]])
* B3678/S34678 ([[Day & Night]])
* B368/S245 ([[Move]], aka [[Morley]])
* B2-a/S12 ([[Just Friends]])
* B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e ([[Snowflakes]])
* R5,C0,M1,S34..58,B34..45,NM ([[Bugs]])

A cached list of all rule-symmetry combinations investigated, sorted by last update, is also available.<ref name="post95134" />{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/abclist</nowiki></tt>}}

==Haul verification==
Hauls for official censuses of [[Life-like cellular automaton|Life-like]] rules with at least one trillion objects are subject to statistical verification and peer review before being committed in order to avoid false data being added to the census. As of April 2, 2019, this includes all official apgsearch-supported CPU symmetries for [[Conway's Game of Life]] as well as B38/S23/C1 ([[Pedestrian Life]]), B3/S01367/C1, B35/S136/C1, B3/S12/C1 ([[Flock]]), B3/S2/C1, and B3/S01357/C1.

==Catagolue as a generic pattern inventory==
Although primarily used for soup-searching in practice, Catagolue can be used as a generic pattern inventory/warehouse, as shown by e.g. the slow salvo data it collected (see above). Users are encouraged come up with their own rulestrings, symmetry types, and object codes:

:''[Catagolue] basically accepts anything that you choose to pass off as a rule name, symmetry type, and apgcode. If you make a search program which produces haul files for your favourite CA, then Catagolue will happily build a distributed census [...]''

:''The search program needn't even be a soup search: if you have a depth-first search program such as gfind or zfind, and you have a correspondence between positions in the search tree and alphanumeric strings (where prefixes correspond to ancestors), then you can conduct a distributed search for (say) width-20 c/6 spaceships using the existing Catagolue framework. If you incorporate all of zfind's command-line hyperparameters (period, offset, memory size, etc.) into the beginning of this string, then you can simply have a 'symmetry' called zfind whose tabulations will include things such as xq7, xq10, xq19 (potentially!), etc. And this will work without changing Catagolue in any way.''

::— [[Adam P. Goucher]]<ref name="post48707" />

This is simplified by the <tt>stdin</tt> symmetries of [[apgsearch]], which accept RLEs from standard input to be used in lieu of random soups. [[Arie Paap]] found a c/4 diagonal [[tubstretcher]] in this manner by piping the output of [[ikpx]] into apgsearch.<ref name="post70977" /> This was notable in that the tubstretcher could neither be found by ikpx (which can only find spaceships) nor apgsearch (searching random soups) in isolation.

===Glider syntheses===
{{alsosee|Tutorials/Glider syntheses#Submitting syntheses to Catagolue}}
Catagolue also contains a database of cheapest known [[glider syntheses]] of various objects (including pseudo-objects) retrieved from both [[Shinjuku]] and [[LifeWiki]], and displays them on the respective object page. A list of objects for which syntheses are available is compiled in the <tt>synthesis-costs</tt> [https://catagolue.hatsya.com/census/b3s23/synthesis-costs symmetry] of B3/S23.<ref name="post74801" />

The [https://catagolue.hatsya.com/syntheses "Syntheses" page] of Catagolue transcludes the <tt>synthesis-costs</tt> census and also includes a text box in which users can submit synthesis components in [[RLE]] form to be added to Catagolue's <tt>readsynth</tt> queue.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/readsynth</nowiki></tt>}} These RLE files are automatically parsed and interpreted by Catagolue's thrice-daily update process, and added to the site if they contain new or improved syntheses.{{refn|group=note|As of August 2020, the synthesis submission box does not allow for [[linear growth]] syntheses to be submitted.<ref name="post81683" /> Instead, these must either be added directly to the Catagolue database or added via editing <tt>diffupdate.py</tt>.<ref name="post101839" />}}

==Contributor engagement==
Contributors to Catagolue have user pages tracking their contributions to the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/user/<user name></nowiki></tt>}} In addition to providing an overview of number of objects submitted recently compared to other users, user pages list important discoveries and awarded badges.

Users are credited for discoveries if they find one of the first 20 occurrences of an interesting object: any [[spaceship]] (other than the [[glider]]), any [[oscillator]], any [[Infinite growth#Linear|linear growth]] pattern, or any sufficiently large (≥[[:Category:Strict still lifes with 30 cells|30-bit]]) [[still life]].

The following badges are currently awarded for contributions to B3/S23/C1:

==Backups==
Catagolue census data for the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1, is backed up remotely every day at 17:29;{{refn|group=note|Ramanujan time, after the [https://en.wikipedia.org/wiki/1729_(number) Hardy–Ramanujan number (1729)] of G. H. Hardy's and Srinivasa Ramanujan's.}} the first such backup was made on September 24, 2015. For other symmetries or rules, a remote backup may be instigated manually by calling the <tt>backupcron</tt> endpoint,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/backupcron/<rule>/<symmetry></nowiki></tt>}} with the desired rule and symmetry. Remote backups can be viewed by appending the date (in [https://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format) to the main census URL.{{refn|group=endpoint|name=backup|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry>-<year>-<month>-<day></nowiki></tt>}}

Backups of the <tt>synthesis-costs</tt> census are automatically made three times a month, specifically on dates ending with a "5", and can be accessed using the <tt>year-month-day</tt> method.{{refn|group=endpoint|name=backup}}

Local backups of Catagolue census data may be made by calling the <tt>textcensus</tt> endpoint for the desired rule and symmetry.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry></nowiki></tt>}} The list of objects returned can be sorted by object frequency,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/sorted</nowiki></tt>}} but this should be avoided when possible to reduce server load.<ref name="calcyman20170129" /> It is also possible to restrict objects returned to a certain prefix,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/<prefix></nowiki></tt>}} or to query the number of objects, grouped by prefix and including a total.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/objcount</nowiki></tt>}}

==Limitations==
{{alsosee|apgsearch#Limitations}}

===Server===
Catagolue does not accept hauls exceeding 1 MiB; additionally, hauls must contains a minimum of 10,000 soups or 250,000 objects.<ref name="calcyman20160630" />

Each tabulation on Catagolue also has a maximum size of 1 MB imposed by Google Cloud Datastore; obscure objects will sometimes be deleted from these tabulations to meet this limit.<ref name="post64739" /> In December 2018, Catagolue switched to a new compression system, allowing certain [[:Category:Oscillators with period 2|period 2]] [[oscillator]]s to be manually readded to the D8_1 and D8_4 censuses without meeting the 1 MB limit.<ref name="post66653" />

===Web frontend===
Although Catagolue verifies that an object in a given rule behaves as specified by its code, the site makes no attempt to reject non-canonical codes (e.g. <tt>xp2_222</tt> rather than <tt>xp2_7</tt> for the [[blinker]]); furthermore, the site accepts various anomalous prefixes (e.g. <tt>xp0</tt> and <tt>xq0</tt>). No attempt is made to normalize or reject anomalous rules (e.g. "<tt>b33s23</tt>"), although a feature is planned to clear out censuses which do not adhere to the [[Catagolue naming conventions]].

Catagolue's <tt>hashsoup</tt> functionality, used for retrieving sample soups from the database,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/hashsoup/<symmetry>/<id>/<rule></nowiki></tt>}} only recognizes official square grid symmetries and D2_xo,{{refn|group=note|D2_xo is simply an orthogonal reflection of the equivalent D2_x soup for the [[Moore neighbourhood]], but functions as a distinct symmetry in hexagonal rules.}} and defaults to C1 for all others. Soups with symmetries exclusive to the [[hexagonal neighbourhood|hexagonal grid]] (i.e. containing <tt>C3</tt>, <tt>C6</tt>, <tt>D6</tt>, or <tt>D12</tt>) must instead be reconstructed using [[lifelib]].<ref name="post66638" />

'''Catagolue'''{{refn|group=note|The name "Catagolue" is an amalgam of "Catalogue" and "GoL" ([[Conway's Game of Life|Game of Life]]).}} is an ongoing distributed [[census]] of naturally occurring [[ash]] objects conducted by [[Adam P. Goucher]], started in late February 2015. The census is primarily focused on asymmetric soups in [[Conway's Game of Life|Conway's Life]], but supports arbitrary [[Life-like cellular automaton|outer-totalistic]] and [[Non-totalistic Life-like cellular automaton|non-totalistic]] rules and a variety of [[symmetry|symmetries]].{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry></nowiki></tt>}} Over 100 users have contributed to the census.

The results are obtained by evolving random [[soup]]s of size 16×16 with [[density]] 0.5 in an infinite planar [[universe]]; as of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types. Submissions of new results (called "hauls") are subjected to both statistical tests and peer-review by other participants before being committed to the census.

Catagolue is primarily fed by [[apgsearch]] 5.x (apgluxe). Each resulting object is identified by [[apgsearch]] by its unique [[apgcode]]; the Catagolue website gives overviews over the various classes of objects found, and provides further information as well as sample soups for each object.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/object/<apgcode>/<rule></nowiki></tt>}} A simple text-based interface for querying sample soups, including their owners, also exists.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/attribute/<apgcode>/<rule>/<symmetry></nowiki></tt>}}

==History==
{{Main|History of Catagolue}}
Catagolue became operative on February 20, 2015.<ref name="calcyman20150220" /> The B3/S23/C1 census reached a total of one trillion objects on April 24, 2015,<ref name="billabob20150424" /> ten trillion objects on September 2, 2015,<ref name="calcyman20150902" /> 100 trillion objects on June 20, 2016,<ref name="applebottom20160620" /> and 200 trillion objects on May 16, 2017.

==Results in Conway's Game of Life==
{{Alsosee|apgsearch#Notable patterns}}

===Asymmetric soups===
{{Alsosee|Most common objects on Catagoluge}}
The default rule/symmetry combination for apgsearch, [[Conway's Game of Life|B3/S23]]/C1, is by far the most popular census on Catagolue. As of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types.<ref name="stats" />

==Other rules==
{{Main|List of rules investigated on Catagolue}}
Catagolue also collects census data on various rules other than Conway's Game of Life. In practice, only non-exploding rules can reasonably be investigated unless a certain symmetry can be assured to never explode.

As of January 15, 2019, Catagolue officially supports the following types of cellular automata:
*Arbitrary [[Life-like cellular automaton|outer-totalistic]] rules.
*[[Isotropic non-totalistic Life-like cellular automaton|Isotropic non-totalistic]] rules. (in [[Hensel notation]])
*[[Isotropic]] [[von Neumann neighbourhood]] rules. (implicitly by isotropic non-totalistic [[Moore neighbourhood]] rules)
*Higher-range outer totalistic (HROT) rules. (up to range 5)
*[[Larger than Life]] rules. (up to range 7)
*Totalistic and isotropic [[hexagonal neighbourhood]] rules.
*[[Generations]] variants of all rules listed above.
*[[Life-like cellular automaton|Outer-totalistic]] [[rulespace|B0 rules]] with two states.
*[[BSFKL]] rules.
*[[Deficient]] rules.
*[[Extended Generations]] rules.
*Custom [[Golly]] ruletables.

{{:Catagolue/Stats|numrules}} rules have been investigated at as of {{:Catagolue/Stats|date}}, including the following close Life variants:

* B3/S238 ([[EightLife]])
* B36/S23 ([[HighLife]])
* B368/S238 ([[LowDeath]])
* B38/S23 ([[Pedestrian Life]])
* B38/S238 ([[HoneyLife]])
* B3/S2-i34q ([[tlife]])
* B36/S2-i34q ([[thighlife]])
* B37/S2-i34q ([[tdrylife]])
* B38/S2-i34q ([[tpedestrianlife]])

Other notable rules investigated include:

* B3/S12 ([[Flock]])
* B3/S13 ([[LowLife]])
* B345/S5 ([[Long Life]])
* B36/S125 ([[2×2]])
* B3678/S34678 ([[Day & Night]])
* B368/S245 ([[Move]], aka [[Morley]])
* B2-a/S12 ([[Just Friends]])
* B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e ([[Snowflakes]])
* R5,C0,M1,S34..58,B34..45,NM ([[Bugs]])

A cached list of all rule-symmetry combinations investigated, sorted by last update, is also available.<ref name="post95134" />{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/abclist</nowiki></tt>}}

==Haul verification==
Hauls for official censuses of [[Life-like cellular automaton|Life-like]] rules with at least one trillion objects are subject to statistical verification and peer review before being committed in order to avoid false data being added to the census. As of April 2, 2019, this includes all official apgsearch-supported CPU symmetries for [[Conway's Game of Life]] as well as B38/S23/C1 ([[Pedestrian Life]]), B3/S01367/C1, B35/S136/C1, B3/S12/C1 ([[Flock]]), B3/S2/C1, and B3/S01357/C1.

==Catagolue as a generic pattern inventory==
Although primarily used for soup-searching in practice, Catagolue can be used as a generic pattern inventory/warehouse, as shown by e.g. the slow salvo data it collected (see above). Users are encouraged come up with their own rulestrings, symmetry types, and object codes:

:''[Catagolue] basically accepts anything that you choose to pass off as a rule name, symmetry type, and apgcode. If you make a search program which produces haul files for your favourite CA, then Catagolue will happily build a distributed census [...]''

:''The search program needn't even be a soup search: if you have a depth-first search program such as gfind or zfind, and you have a correspondence between positions in the search tree and alphanumeric strings (where prefixes correspond to ancestors), then you can conduct a distributed search for (say) width-20 c/6 spaceships using the existing Catagolue framework. If you incorporate all of zfind's command-line hyperparameters (period, offset, memory size, etc.) into the beginning of this string, then you can simply have a 'symmetry' called zfind whose tabulations will include things such as xq7, xq10, xq19 (potentially!), etc. And this will work without changing Catagolue in any way.''

::— [[Adam P. Goucher]]<ref name="post48707" />

This is simplified by the <tt>stdin</tt> symmetries of [[apgsearch]], which accept RLEs from standard input to be used in lieu of random soups. [[Arie Paap]] found a c/4 diagonal [[tubstretcher]] in this manner by piping the output of [[ikpx]] into apgsearch.<ref name="post70977" /> This was notable in that the tubstretcher could neither be found by ikpx (which can only find spaceships) nor apgsearch (searching random soups) in isolation.

===Glider syntheses===
{{alsosee|Tutorials/Glider syntheses#Submitting syntheses to Catagolue}}
Catagolue also contains a database of cheapest known [[glider syntheses]] of various objects (including pseudo-objects) retrieved from both [[Shinjuku]] and [[LifeWiki]], and displays them on the respective object page. A list of objects for which syntheses are available is compiled in the <tt>synthesis-costs</tt> [https://catagolue.hatsya.com/census/b3s23/synthesis-costs symmetry] of B3/S23.<ref name="post74801" />

The [https://catagolue.hatsya.com/syntheses "Syntheses" page] of Catagolue transcludes the <tt>synthesis-costs</tt> census and also includes a text box in which users can submit synthesis components in [[RLE]] form to be added to Catagolue's <tt>readsynth</tt> queue.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/readsynth</nowiki></tt>}} These RLE files are automatically parsed and interpreted by Catagolue's thrice-daily update process, and added to the site if they contain new or improved syntheses.{{refn|group=note|As of August 2020, the synthesis submission box does not allow for [[linear growth]] syntheses to be submitted.<ref name="post81683" /> Instead, these must either be added directly to the Catagolue database or added via editing <tt>diffupdate.py</tt>.<ref name="post101839" />}}

==Contributor engagement==
Contributors to Catagolue have user pages tracking their contributions to the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/user/<user name></nowiki></tt>}} In addition to providing an overview of number of objects submitted recently compared to other users, user pages list important discoveries and awarded badges.

Users are credited for discoveries if they find one of the first 20 occurrences of an interesting object: any [[spaceship]] (other than the [[glider]]), any [[oscillator]], any [[Infinite growth#Linear|linear growth]] pattern, or any sufficiently large (≥[[:Category:Strict still lifes with 30 cells|30-bit]]) [[still life]].

The following badges are currently awarded for contributions to B3/S23/C1:

* [[File:Conchita.png]] Conchita{{refn|group=note|The "Conchita" badge is named after [https://en.wikipedia.org/wiki/Conchita_Wurst Conchita Wurst], the Austrian singer who won the 2014 Eurovision Song Contest with the song "Rise Like a Phoenix".}}: find a soup containing a [[phoenix 1|phoenix]].
* [[File:GeminiTheBadge.png]] Gemini: discover a new [[twin bees shuttle]] variant.
* [[File:Gigamyriad.png]] Gigamyriad: contribute 10<sup>13</sup> objects.
* [[File:Hitchhiker.png]] Hitchhiker{{refn|group=note|The "Hitchhiker" badge is a reference to [https://en.wikipedia.org/wiki/The_Hitchhiker's_Guide_to_the_Galaxy ''The Hitchhiker's Guide to the Galaxy''] franchise.}}: find a soup containing a [[Kok's galaxy]].<ref name="post48036" />{{refn|group=note|The "Hitchhiker" badge has not been awarded as of March 5, 2018.}}
* [[File:Limitless.png]] Limitless: observe a new natural [[infinite-growth pattern]].
* [[File:Loafer_badge.png]] Loafer: discover a natural [[loafer]].
* [[File:Monarchist.png]] Monarchist: discover a new [[queen bee shuttle]] variant.
* [[File:Sprotsmanship.png]] Sprotsmanship{{refn|group=note|Sic; a deliberate reference to [https://meta.mathoverflow.net/posts/445/revisions this post on MathOverflow] and the comments it attracted.}}: contribute one third of a trillion objects to a different rule or symmetry.
* [[File:Trillionaire.png]] Trillionaire: contribute one trillion objects.
* [[File:Voyager.png]] Voyager: find one of the first twenty occurrences of a [[spaceship]].

Interesting new objects are additionally announced on Twitter by an unofficial Twitter bot.

==Backups==
Catagolue census data for the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1, is backed up remotely every day at 17:29;{{refn|group=note|Ramanujan time, after the [https://en.wikipedia.org/wiki/1729_(number) Hardy–Ramanujan number (1729)] of G. H. Hardy's and Srinivasa Ramanujan's.}} the first such backup was made on September 24, 2015. For other symmetries or rules, a remote backup may be instigated manually by calling the <tt>backupcron</tt> endpoint,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/backupcron/<rule>/<symmetry></nowiki></tt>}} with the desired rule and symmetry. Remote backups can be viewed by appending the date (in [https://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format) to the main census URL.{{refn|group=endpoint|name=backup|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry>-<year>-<month>-<day></nowiki></tt>}}

Backups of the <tt>synthesis-costs</tt> census are automatically made three times a month, specifically on dates ending with a "5", and can be accessed using the <tt>year-month-day</tt> method.{{refn|group=endpoint|name=backup}}

Local backups of Catagolue census data may be made by calling the <tt>textcensus</tt> endpoint for the desired rule and symmetry.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry></nowiki></tt>}} The list of objects returned can be sorted by object frequency,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/sorted</nowiki></tt>}} but this should be avoided when possible to reduce server load.<ref name="calcyman20170129" /> It is also possible to restrict objects returned to a certain prefix,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/<prefix></nowiki></tt>}} or to query the number of objects, grouped by prefix and including a total.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/objcount</nowiki></tt>}}

==Limitations==
{{alsosee|apgsearch#Limitations}}

===Server===
Catagolue does not accept hauls exceeding 1 MiB; additionally, hauls must contains a minimum of 10,000 soups or 250,000 objects.<ref name="calcyman20160630" />

Each tabulation on Catagolue also has a maximum size of 1 MB imposed by Google Cloud Datastore; obscure objects will sometimes be deleted from these tabulations to meet this limit.<ref name="post64739" /> In December 2018, Catagolue switched to a new compression system, allowing certain [[:Category:Oscillators with period 2|period 2]] [[oscillator]]s to be manually readded to the D8_1 and D8_4 censuses without meeting the 1 MB limit.<ref name="post66653" />

===Web frontend===
Although Catagolue verifies that an object in a given rule behaves as specified by its code, the site makes no attempt to reject non-canonical codes (e.g. <tt>xp2_222</tt> rather than <tt>xp2_7</tt> for the [[blinker]]); furthermore, the site accepts various anomalous prefixes (e.g. <tt>xp0</tt> and <tt>xq0</tt>). No attempt is made to normalize or reject anomalous rules (e.g. "<tt>b33s23</tt>"), although a feature is planned to clear out censuses which do not adhere to the [[Catagolue naming conventions]].

Catagolue's <tt>hashsoup</tt> functionality, used for retrieving sample soups from the database,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/hashsoup/<symmetry>/<id>/<rule></nowiki></tt>}} only recognizes official square grid symmetries and D2_xo,{{refn|group=note|D2_xo is simply an orthogonal reflection of the equivalent D2_x soup for the [[Moore neighbourhood]], but functions as a distinct symmetry in hexagonal rules.}} and defaults to C1 for all others. Soups with symmetries exclusive to the [[hexagonal neighbourhood|hexagonal grid]] (i.e. containing <tt>C3</tt>, <tt>C6</tt>, <tt>D6</tt>, or <tt>D12</tt>) must instead be reconstructed using [[lifelib]].<ref name="post66638" />

'''Catagolue'''{{refn|group=note|The name "Catagolue" is an amalgam of "Catalogue" and "GoL" ([[Conway's Game of Life|Game of Life]]).}} is an ongoing distributed [[census]] of naturally occurring [[ash]] objects conducted by [[Adam P. Goucher]], started in late February 2015. The census is primarily focused on asymmetric soups in [[Conway's Game of Life|Conway's Life]], but supports arbitrary [[Life-like cellular automaton|outer-totalistic]] and [[Non-totalistic Life-like cellular automaton|non-totalistic]] rules and a variety of [[symmetry|symmetries]].{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry></nowiki></tt>}} Over 100 users have contributed to the census.

The results are obtained by evolving random [[soup]]s of size 16×16 with [[density]] 0.5 in an infinite planar [[universe]]; as of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types. Submissions of new results (called "hauls") are subjected to both statistical tests and peer-review by other participants before being committed to the census.

Catagolue is primarily fed by [[apgsearch]] 5.x (apgluxe). Each resulting object is identified by [[apgsearch]] by its unique [[apgcode]]; the Catagolue website gives overviews over the various classes of objects found, and provides further information as well as sample soups for each object.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/object/<apgcode>/<rule></nowiki></tt>}} A simple text-based interface for querying sample soups, including their owners, also exists.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/attribute/<apgcode>/<rule>/<symmetry></nowiki></tt>}}

The default rule/symmetry combination for apgsearch, [[Conway's Game of Life|B3/S23]]/C1, is by far the most popular census on Catagolue. As of {{:Catagolue/Stats|date}}, at least {{:Catagolue/Stats|numsoups}} soups have been investigated by the census's participants, yielding a total of at least {{:Catagolue/Stats|numobjects}} objects of {{:Catagolue/Stats|distinctobjects}} distinct types.<ref name="stats" />

A view of the combined statistics for the C1 and G1 symmetries can be seen in the [https://catagolue.hatsya.com/census/b3s23/asymmetric-soups <tt>asymmetric-soups</tt>] census.<ref name="post93707" />

==Other rules==
{{Main|List of rules investigated on Catagolue}}
Catagolue also collects census data on various rules other than Conway's Game of Life. In practice, only non-exploding rules can reasonably be investigated unless a certain symmetry can be assured to never explode.

As of January 15, 2019, Catagolue officially supports the following types of cellular automata:
*Arbitrary [[Life-like cellular automaton|outer-totalistic]] rules.
*[[Isotropic non-totalistic Life-like cellular automaton|Isotropic non-totalistic]] rules. (in [[Hensel notation]])
*[[Isotropic]] [[von Neumann neighbourhood]] rules. (implicitly by isotropic non-totalistic [[Moore neighbourhood]] rules)
*Higher-range outer totalistic (HROT) rules. (up to range 5)
*[[Larger than Life]] rules. (up to range 7)
*Totalistic and isotropic [[hexagonal neighbourhood]] rules.
*[[Generations]] variants of all rules listed above.
*[[Life-like cellular automaton|Outer-totalistic]] [[rulespace|B0 rules]] with two states.
*[[BSFKL]] rules.
*[[Deficient]] rules.
*[[Extended Generations]] rules.
*Custom [[Golly]] ruletables.

{{:Catagolue/Stats|numrules}} rules have been investigated at as of {{:Catagolue/Stats|date}}, including the following close Life variants:

* B3/S238 ([[EightLife]])
* B36/S23 ([[HighLife]])
* B368/S238 ([[LowDeath]])
* B38/S23 ([[Pedestrian Life]])
* B38/S238 ([[HoneyLife]])
* B3/S2-i34q ([[tlife]])
* B36/S2-i34q ([[thighlife]])
* B37/S2-i34q ([[tdrylife]])
* B38/S2-i34q ([[tpedestrianlife]])

Other notable rules investigated include:

* B3/S12 ([[Flock]])
* B3/S13 ([[LowLife]])
* B345/S5 ([[Long Life]])
* B36/S125 ([[2×2]])
* B3678/S34678 ([[Day & Night]])
* B368/S245 ([[Move]], aka [[Morley]])
* B2-a/S12 ([[Just Friends]])
* B2ci3ai4c8/S02ae3eijkq4iz5ar6i7e ([[Snowflakes]])
* R5,C0,M1,S34..58,B34..45,NM ([[Bugs]])

A cached list of all rule-symmetry combinations investigated, sorted by last update, is also available.<ref name="post95134" />{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/abclist</nowiki></tt>}}

==Haul verification==
Hauls for official censuses of [[Life-like cellular automaton|Life-like]] rules with at least one trillion objects are subject to statistical verification and peer review before being committed in order to avoid false data being added to the census. As of April 2, 2019, this includes all official apgsearch-supported CPU symmetries for [[Conway's Game of Life]] as well as B38/S23/C1 ([[Pedestrian Life]]), B3/S01367/C1, B35/S136/C1, B3/S12/C1 ([[Flock]]), B3/S2/C1, and B3/S01357/C1.

==Catagolue as a generic pattern inventory==
Although primarily used for soup-searching in practice, Catagolue can be used as a generic pattern inventory/warehouse, as shown by e.g. the slow salvo data it collected (see above). Users are encouraged come up with their own rulestrings, symmetry types, and object codes:

:''[Catagolue] basically accepts anything that you choose to pass off as a rule name, symmetry type, and apgcode. If you make a search program which produces haul files for your favourite CA, then Catagolue will happily build a distributed census [...]''

:''The search program needn't even be a soup search: if you have a depth-first search program such as gfind or zfind, and you have a correspondence between positions in the search tree and alphanumeric strings (where prefixes correspond to ancestors), then you can conduct a distributed search for (say) width-20 c/6 spaceships using the existing Catagolue framework. If you incorporate all of zfind's command-line hyperparameters (period, offset, memory size, etc.) into the beginning of this string, then you can simply have a 'symmetry' called zfind whose tabulations will include things such as xq7, xq10, xq19 (potentially!), etc. And this will work without changing Catagolue in any way.''

::— [[Adam P. Goucher]]<ref name="post48707" />

This is simplified by the <tt>stdin</tt> symmetries of [[apgsearch]], which accept RLEs from standard input to be used in lieu of random soups. [[Arie Paap]] found a c/4 diagonal [[tubstretcher]] in this manner by piping the output of [[ikpx]] into apgsearch.<ref name="post70977" /> This was notable in that the tubstretcher could neither be found by ikpx (which can only find spaceships) nor apgsearch (searching random soups) in isolation.

===Glider syntheses===
{{alsosee|Tutorials/Glider syntheses#Submitting syntheses to Catagolue}}
Catagolue also contains a database of cheapest known [[glider syntheses]] of various objects (including pseudo-objects) retrieved from both [[Shinjuku]] and [[LifeWiki]], and displays them on the respective object page. A list of objects for which syntheses are available is compiled in the <tt>synthesis-costs</tt> [https://catagolue.hatsya.com/census/b3s23/synthesis-costs symmetry] of B3/S23.<ref name="post74801" />

The [https://catagolue.hatsya.com/syntheses "Syntheses" page] of Catagolue transcludes the <tt>synthesis-costs</tt> census and also includes a text box in which users can submit synthesis components in [[RLE]] form to be added to Catagolue's <tt>readsynth</tt> queue.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/readsynth</nowiki></tt>}} These RLE files are automatically parsed and interpreted by Catagolue's thrice-daily update process, and added to the site if they contain new or improved syntheses.{{refn|group=note|As of August 2020, the synthesis submission box does not allow for [[linear growth]] syntheses to be submitted.<ref name="post81683" /> Instead, these must either be added directly to the Catagolue database or added via editing <tt>diffupdate.py</tt>.<ref name="post101839" />}}

==Contributor engagement==
Contributors to Catagolue have user pages tracking their contributions to the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/user/<user name></nowiki></tt>}} In addition to providing an overview of number of objects submitted recently compared to other users, user pages list important discoveries and awarded badges.

Users are credited for discoveries if they find one of the first 20 occurrences of an interesting object: any [[spaceship]] (other than the [[glider]]), any [[oscillator]], any [[Infinite growth#Linear|linear growth]] pattern, or any sufficiently large (≥[[:Category:Strict still lifes with 30 cells|30-bit]]) [[still life]].

The following badges are currently awarded for contributions to B3/S23/C1:

==Backups==
Catagolue census data for the main [[Conway's Game of Life|Conway Life]] census, B3/S23/C1, is backed up remotely every day at 17:29;{{refn|group=note|Ramanujan time, after the [https://en.wikipedia.org/wiki/1729_(number) Hardy–Ramanujan number (1729)] of G. H. Hardy's and Srinivasa Ramanujan's.}} the first such backup was made on September 24, 2015. For other symmetries or rules, a remote backup may be instigated manually by calling the <tt>backupcron</tt> endpoint,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/backupcron/<rule>/<symmetry></nowiki></tt>}} with the desired rule and symmetry. Remote backups can be viewed by appending the date (in [https://en.wikipedia.org/wiki/ISO_8601 ISO 8601] format) to the main census URL.{{refn|group=endpoint|name=backup|<tt><nowiki>https://catagolue.hatsya.com/census/<rule>/<symmetry>-<year>-<month>-<day></nowiki></tt>}}

Backups of the <tt>synthesis-costs</tt> census are automatically made three times a month, specifically on dates ending with a "5", and can be accessed using the <tt>year-month-day</tt> method.{{refn|group=endpoint|name=backup}}

Local backups of Catagolue census data may be made by calling the <tt>textcensus</tt> endpoint for the desired rule and symmetry.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry></nowiki></tt>}} The list of objects returned can be sorted by object frequency,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/sorted</nowiki></tt>}} but this should be avoided when possible to reduce server load.<ref name="calcyman20170129" /> It is also possible to restrict objects returned to a certain prefix,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/<prefix></nowiki></tt>}} or to query the number of objects, grouped by prefix and including a total.{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/textcensus/<rule>/<symmetry>/objcount</nowiki></tt>}}

==Limitations==
{{alsosee|apgsearch#Limitations}}

===Server===
Catagolue does not accept hauls exceeding 1 MiB; additionally, hauls must contains a minimum of 10,000 soups or 250,000 objects.<ref name="calcyman20160630" />

Each tabulation on Catagolue also has a maximum size of 1 MB imposed by Google Cloud Datastore; obscure objects will sometimes be deleted from these tabulations to meet this limit.<ref name="post64739" /> In December 2018, Catagolue switched to a new compression system, allowing certain [[:Category:Oscillators with period 2|period 2]] [[oscillator]]s to be manually readded to the D8_1 and D8_4 censuses without meeting the 1 MB limit.<ref name="post66653" />

===Web frontend===
Although Catagolue verifies that an object in a given rule behaves as specified by its code, the site makes no attempt to reject non-canonical codes (e.g. <tt>xp2_222</tt> rather than <tt>xp2_7</tt> for the [[blinker]]); furthermore, the site accepts various anomalous prefixes (e.g. <tt>xp0</tt> and <tt>xq0</tt>). No attempt is made to normalize or reject anomalous rules (e.g. "<tt>b33s23</tt>"), although a feature is planned to clear out censuses which do not adhere to the [[Catagolue naming conventions]].

Catagolue's <tt>hashsoup</tt> functionality, used for retrieving sample soups from the database,{{refn|group=endpoint|<tt><nowiki>https://catagolue.hatsya.com/hashsoup/<symmetry>/<id>/<rule></nowiki></tt>}} only recognizes official square grid symmetries and D2_xo,{{refn|group=note|D2_xo is simply an orthogonal reflection of the equivalent D2_x soup for the [[Moore neighbourhood]], but functions as a distinct symmetry in hexagonal rules.}} and defaults to C1 for all others. Soups with symmetries exclusive to the [[hexagonal neighbourhood|hexagonal grid]] (i.e. containing <tt>C3</tt>, <tt>C6</tt>, <tt>D6</tt>, or <tt>D12</tt>) must instead be reconstructed using [[lifelib]].<ref name="post66638" />

'''c/5 diagonal''' is a diagonal [[speed]] that is equivalent to one fifth of the speed of light.

==Spaceships==
The first c/5 diagonal [[spaceship]] to be discovered was [[295P5H1V1]] and was found by [[Jason Summers]] on November 22, {{year|2000}}.<ref>{{CiteSummersPattern|name=jslife}}</ref> No other spaceships of this speed were discovered until January 8, {{year|2005}}, when Jason summers found the much smaller [[86P5H1V1]]. In July {{year|2006}} [[Nicolay Beluchenko]] discovered three new c/5 diagonal spaceships, including the asymmetric [[67P5H1V1]].<ref>{{Cite web|url=http://pentadecathlon.com/lifeNews/2006/07/new_c5_diagonal_spaceships_1.html|title=New c/5 Diagonal Spaceships|author=Heinrich Koenig|publisher=Game of Life News|date=July 15, 2006}}</ref> The smallest known c/5 diagonal spaceship, [[58P5H1V1]], was discovered by [[Matthias Merzenich]] on September 5, {{year|2010}}.<ref name="pd20110126" />

After a gap of several years, on March 26-27, {{year|2020}}, AforAmpere found new c/5 diagonal ships with a different shape from previous discoveries.<ref name="post92434" />

The first [[glider synthesis]] for a c/5 diagonal spaceship (58P5H1V1) was found by [[Goldtiger997]] and [[Tanner Jacobi]] in April {{year|2020}}.<ref name="post93110" /><ref name="post93167" />

==Wickstretchers==

The first c/5 diagonal [[wickstretcher]] was found by Matthias Merzenich on January 26, {{year|2011}}.<ref name="pd20110126" /> It consists of a [[tagalong]] pulled by two copies of 58P5H1V1 that stretches two [[tub]]s.

Wolfram's classification

2021-05-07T22:28:03Z

Cgoler2:

{{Glossary}}
A [[cellular automaton]], according to '''[[Stephen Wolfram]]'s 1983 classification scheme''', belongs to any of the four classes judging from its behaviour.

==Class one cellular automata==

'''Class one''' cellular automata are those where the development of all [[pattern]]s tends towards [[vacuum (empty space)|vacuum]].

Class one has many similarities to class two cellular automata. It is in several cases simple to prove that no [[infinite growth|growth]] pattern can exist in a [[Life-like]] or closely related cellular automaton. Showing the nonexistence of [[still life]]s or [[oscillator]]s can be, however, more difficult. As such, it can be difficult to distinguish class two CA whose [[ash]] has extremely low [[density]] from class one.

It is debatable whether [[agar]] solutions are sufficient to claim a CA as class two and not class one. As an extreme example, in the Life-like CA B/S8, exactly one pattern exists that does not evolve to vacuum: "antivacuum", the infinite field of ''live'' cells.

Given their highly predictable nature, there has been very little interest in detailed investigation of class one automata, and none appear to have established names.{{citation needed}}

==Class two cellular automata==

'''Class two''' cellular automata are those where the development of all patterns tends toward simple stationary ash — either constellations of separate still lives and oscillators, or larger regions of stable and oscillating cells.

A simple condition for considering a Life-like cellular automaton to be either class two or class one is the absense of birth conditions capable of extending the pattern's [[bounding box]]: B0, B1, B2 or B3. Beyond this, positively identifying a rule as class two is mostly not an exact science.

The [[Vote]] rule (B5678/S45678) is one of the better known provably class two cellular automata.

==Class three cellular automata==

'''Class three''' cellular automata are those where most patterns tend towards [[chaotic growth|chaotic]], seemingly infinite growth. They are thus the polar opposite of class one CA. The term '''explosive''' is frequently applied to these rules or patterns in them.

The definition of "most" is not exact. Several class three rules have only been identified as such in retrospect, having been previously considered class four cellular automata; since most ''small'' patterns may in fact stabilize. An early example is 34 Life. Arguably [[HighLife]] may be an example as well, as the small natural [[replicator]] means that sufficiently large patterns tend towards infinite growth.

A subdivision, not quite exact, could be made between class three rules that produce "active" chaos, and those that produce a stable mass of live cells (often with encased holes or oscillators).

Class three CA known in detail include:
{| class="wikitable"
|-
! [[Rulestring]] !! Name !! Character !! [[Still life]]s !! [[Oscillator]]s !! [[Spaceship]]s !! Orderly [[infinite growth]] patterns
|-
| B2/S || [[Seeds]] || Active || no || yes || yes || yes<br/>(guns, puffers, rakes)
|-
| B2/S0 || [[Live Free or Die]] || Active || yes ([[dot]]) || yes || yes || yes<br/>(guns, puffers, rakes)
|-
| B3/S023 || [[DotLife]] || Active || yes || yes || yes || yes
|-
| B37/S23 || [[DryLife]] || Active || yes || yes || yes || yes
|-
| B34/S34 || [[3-4 Life]] || Active || yes ([[block]]) || yes || yes || ?
|-
| B35678/S5678 || [[Diamoeba]] || Stable || no || yes || yes || yes<br/>(wickstretchers, spacefillers)
|-
| B3/S012345678 || [[Life without death]] || Stable || yes || no || no || yes<br/>(ladders)
|}

Some others with established names:
{| class="wikitable"
|-
! Rulestring !! Name !! Character
|-
| B234/S || [[Serviettes]] || Active
|-
| B3/S1234 || [[Mazectric]] || Stable
|-
| B3/S12345 || [[Maze]] || Stable
|-
| B3/S45678 || [[Coral]] || Stable
|}

==Class four cellular automata==

'''Class four''' cellular automata are those where most patterns tend towards a mixture of order and randomness. In microscopic scale (that is, not considering meta-pattern constructions like [[0E0P metacell]]), [[Conway's Game of Life]] falls under this class.

Bounding diamond

2021-05-06T22:57:12Z

Cgoler2:

The '''Bounding diamond''' of a pattern is the smallest diamond that fits the entire object. The diamond is diagonal lines meeting up with a side length of 1 or 2 depending on the size. It is useful for seeing how close a [[glider]] can be to an object without colliding.

The [[block]], [[tub]], [[pond]] and generation 5 of the [[T-tetromino]] represent the edges of the bounding diamond of width 2, 3, 4 and 5 respectively. The "octagon" phase of the [[octagon II]] represent the edges of the bounding diamond of width 8.

'''38P7.2''' is an unnamed {{period|7}} [[oscillator]] discovered by [[Nicolay Beluchenko]] on February 17, {{year|2009}}.<ref>{{CiteSummersPattern|name=all-osc}}</ref> It provides four [[spark]]s in [[generation]] 4 that are useful in creating [[p7 bumper]] as well as non-trivial oscillators of higher periods such as [[snacker on 38P7.2]]. A variation of this oscillator can be created by displacing one half of the oscillator by two [[cell]]s.

It first appeared [[semi-natural]]ly in March {{year|2016}}.<ref name="post28846" /> [[gmc_nxtman]] found an {{gliders|18}} [[synthesis]] of this oscillator on August 13, {{year|2017}}.<ref name="post48743" /> [[Goldtiger997]] improved this to {{gliders|14|brief}} gliders on February 12, {{year|2018}}.<ref name="post56409" />

In March {{year|2018}}, [[Josh Ball]] found a pattern that can be stabilized by copies of 38P7.2 without [[block]]s.<ref name="post58484" />
