The '''Snark''' is a 90° [[Stable reflector|stable glider reflector]] discovered by [[Mike Playle]] on April 25, {{year|2013}}.<ref name="post7819" /> It is made up of two [[eater 1]]s, a [[block]] and a [[31.4]], the "heart" of the Snark. It is currently the fastest and the smallest 90° stable [[glider]] reflector, both in terms of the [[population]] and the [[bounding box]]. Another commonly-used stabilization of the [[catalyst]] is 34 bits, and many other variants are available. For a [[color-changing]] one, see the reflector in the [[stable reflector]] article, or a periodic [[bouncer]].

The base [[reaction]] was discovered by [[Dietrich Leithner]] about {{year|1998}}, but it consumed another block.<ref name="post1939" /> A catalyst that could restore the block was found with [[Bellman]], a program for searching catalytic reactions developed by Mike Playle. Prior to that, some attempts like [[p4 reflector]] were made with periodic [[sparker]]s.

Given its small [[repeat time]], the Snark enabled [[adjustable glider loop]] [[oscillator]]s of previously unknown [[period]]s of {{period|43|brief}} and {{period|53|brief}} to be constructed.<ref name="post7820" /> It also made most large symmetrical [[Herschel loop]] [[gun]]s obsolete, since it is now possible to make use of the [[Herschel]] gliders with a shorter path of the Herschel track itself.<ref name="post7901" />

The {{POTY|year=2013|rank=1}}

While the repeat time is 43, a continuous period-38 stream triples the period to 114, while a continuous period-41 stream quadruples the period to 164. A period-42 stream creates an extraneous honey farm, which can be deleted with a block, doubling the period to 84; this is used in the smallest period-84 glider gun.

'''Blocker''' is a {{period|8}} [[oscillator]] found by [[Robert Wainwright]].<ref>{{CiteHickersonOscillators|accessdate=March 14, 2020}}</ref> It is a useful dot [[sparker]] consisting of two [[block]]s [[Hassler|hassling]] an unnamed object which is a dying spark. It reappears halfway through its cycle rotated 180 degrees.

Blockers can also be infinitely connected by "sharing" blocks, as long as adjacent reactions are no more than one phase apart. They can also be connected with [[Coe's p8]], which uses blocks as hasslers in a similar manner.

The '''Acorn''' is a [[methuselah]] found by [[Charles Corderman]]. It was discovered no later than {{year|1971}}<ref name=Lifeline2>[[Lifeline Volume 2]], p. 6</ref>, though its exact year of discovery is unknown. Its maximum population, 1057, occurs in generation 4408.<ref name=Lifeline3>[[Lifeline Volume 3]], p. 12</ref> It is composed of 2 or 3 sparks, depending on how you count them. The left spark can be flipped to create an [[isomer]] that evolves the same way, and can be replaced by a [[V spark]] pointing left.

==Stable pattern==
The stable pattern that results from the acorn has 633 [[cell]]s and covers an area of 215 by 168 cells; it consists of 41 [[blinker]]s (including four [[traffic light]]s), 34 [[block]]s, 30 [[beehive]]s (including one [[honey farm]]), 13 [[glider]]s, eight [[boat]]s, five [[loaf|loaves]], three [[ship]]s, two [[barge]]s, two [[pond]]s and a [[mango]].<ref>{{cite web|url=http://pentadecathlon.com/lifeNews/2005/02/new_methuselah_records.html |title=New Methuselah Records |author=Koenig, H. |date=February 21, 2005 |accessdate=January 24, 2009}}</ref> An [[eater 1]] is temporarily formed at the north side in generation 2661, but does not survive after generation 3925.

==Moving old pages==
The issue of being unable to move certain old pages is [https://www.conwaylife.com/forums/viewtopic.php?f=4&t=4219 well-known], ever since the wiki was updated in October 2019 to the then-latest version of MediaWiki. Unfortunately, Nathaniel never got around to trying out some of the proposed solutions. This has led to quite a few redlinks throughout the wiki, since dozens of pattern pages have been renamed without their image pages being updated accordingly, and I've been hesitant to upload new versions because I don't want to clutter the wiki with duplicate files and because I know that the solution could very well be extremely easy to implement.

One-cell-thick pattern

2021-10-17T17:35:20Z

Moonsheep: Updated the Sierpinski triangle image. Uploaded as a separate file since I was getting an error trying to update the old one.

{{Glossary}}
A '''one-cell-thick pattern''' is a [[pattern]] that is only one [[cell]] thick; that is, it is contained entirely within one dimension of the [[Conway's Game of Life|Life]] plane. Put another way, it is a pattern with [[bounding box]] of the form ''y''×1 for some natural number ''y''. Because of their size restriction, exhaustive computer searches have been carried out to explore unidimensional patterns up to size about 40×1. Despite their inherent limitations, unidimensional patterns can exhibit quite complex behavior, even at reasonably small sizes.

Naively, one would assume that searching all ''y''×1 patterns would require O(2''y'') time. However, all such patterns containing one-cell and two-cell islands can be discarded, which reduces the search time to O(φ''y'').{{refn|group=note|Here, φ = 0.5 · (1 + 5½) ≈ 1.6180339887498948482... is the golden ratio.}}
Callahan employed this optimisation in his search for unidimensional infinite-growth patterns.

==Infinite growth==
[[Image:Unidimensional_infinite_gen2000.png|thumb|right|200x150px|Generation 2000 of Callahan's pattern]]In May {{year|1998}}, [[Stephen Silver]] produced a one cell thick pattern that exhibits infinite growth, following a conjecture of [[Nick Gotts]] that such patterns exist. This pattern was extremely large (12470×1 in the first version, reduced to 5447×1 the following day).<ref>{{Cite web|url=http://www.ericweisstein.com/encyclopedias/life/InfiniteGrowth.html|title=Infinite Growth|author=Eric Weisstein|publisher=Eric Weisstein's Treasure Trove of Life C.A.|accessdate=May 27, 2009}}</ref>

In October {{year|1998}}, [[Paul Callahan]] performed an exhaustive computer search to find the following pattern that exhibits infinite growth. It is one of the most well-known one cell thick patterns, and Callahan showed that it is the smallest such one cell thick pattern (in terms of its bounding box) to exhibit [[infinite growth]]. It contains 28 alive [[cell]]s and has a 39×1 bounding box.
[[Image:Unidimensional_infinite.png|framed|center|Paul Callahan's one cell thick infinite growth pattern {{JavaRLE|unidimensionalinfinitegrowth}}]]

Indeed, this pattern produces two [[block-laying switch engine]]s at about [[generation]] 700. The image to the right shows what it looks like at generation 2000.

==Quadratic growth==
In April 2011, [[Stephen Silver]] constructed a [[1xN quadratic growth|unidimensional pattern based on a breeder by Nick Gotts]], over a million cells long, which displays [[quadratic growth]].<ref>{{Cite web|url=http://pentadecathlon.com/lifeNews/2011/05/quadratic_population_growth_fr.html|title=Quadratic population growth from one row of cells|author=Stephen Silver|publisher=Heinrich Koenig, LifeNews weblog|accessdate=June 9, 2013}}</ref>

In November 2014, [[Chris Cain]] constructed a 7242×1 [[quadratic growth]] pattern.<ref>{{Cite web|url=http://conwaylife.com/forums/viewtopic.php?f=2&t=1406&p=14164#p14226|title=Re: Making switch-engines|author=Chris Cain|date=November 9, 2014|accessdate=August 13, 2015}}</ref> In October 2015, he reduced this pattern to 2596×1.<ref>{{Cite web|url=http://conwaylife.com/forums/viewtopic.php?f=2&t=1406&p=14164#p51585|title=Re: Making switch-engines|author=Chris Cain|date=October 3, 2017|accessdate=February 10, 2018}}</ref>

==With all cells alive==
Making the restriction that all cells in the unidimensional pattern must be alive (that is, the pattern is a y×1 rectangle of alive cells) still leaves some interesting patterns. The majority of small patterns of this type quickly decay into [[constellation]]s made up of [[blinker]]s, [[block]]s and other common [[still life]]s and [[oscillator]]s, but some interesting cases are considered here. The simplest interesting such pattern is the y=3 case, which is simply the [[blinker]] (the only known finite oscillator that is one cell thick in one of its [[phase]]s). The next interesting such pattern comes when y=10, which rapidly evolves into a [[pentadecathlon]].
[[Image:Unidimensional_pentadecathlon.png|framed|center|A pentadecathlon predecessor {{JavaRLE|unidimensionalpentadecathlon|brief}}]]

The 41×1 box creates four [[pulsar]]s after about 200 generations -- this is the smallest one-cell thick pattern with all of its cells alive that creates an oscillator of period other than 2 or 15 (pulsars are also created by a line of length 135<ref>{{Cite web|url=http://sourceforge.net/forum/forum.php?thread_id=2086345&forum_id=467856|title=Sierpiński triangle in Life|author=Richard Hendricks|accessdate=June 16, 2009|date=June 20, 2008}}</ref>). The shortest such pattern that creates a [[toad]] has length 96, and the shortest such pattern that creates a [[spark coil]] has length 72. The shortest such pattern that produces an escaping [[glider]] has a width of 56.<ref>{{Cite web|url=http://www.conwaylife.com/forums/viewtopic.php?f=2&t=48|title=One cell thick patterns|publisher=ConwayLife.com forums|author=Oscar Cunningham|date=March 29, 2009|accessdate=May 27, 2009}}</ref> It produces four gliders at about generation 100.
[[Image:Unidimensional_solid_glider.png|framed|center|Unidimensional pattern that produces four gliders {{JavaRLE|unidimensionalfourgliders}}]]

The period of the pattern that results from the evolution of a y×1 rectangle for y = 1, 2, 3, ... is given by 1, 1, 2, 1, 2, 1, 1, 1, 2, 15, 2, 1, 2, 1, 1, ... (Sloane's {{OEIS|A061342}}). As the length of the rectangle increases, its evolution becomes increasingly predictable. A long row of live cells will eventually form a shape resembling two copies of the [http://en.wikipedia.org/wiki/Sierpinski_triangle Sierpinski Triangle]. In the process of making those triangles, it will send away several [[glider]]s and form [[bi-block]]s in the middle of the triangles.
[[Image:Sierpinski.png|thumb|center|Generation 10,000,000 (escaping gliders omitted) of a row of 1,048,567 (2^20) live cells]]

==Other examples==
{{Ambox|text=This article needs to be expanded with: '''[[14911M]]'''.}}
Some other interesting examples of one cell thick patterns include the following [[predecessor]] of a [[tumbler]], which was found during Paul Callahan's computer search in October 1998. It has 27 live cells and fits in a 36×1 bounding box.<ref>{{CiteSummersPattern|name=jslife}}</ref>
[[Image:Unidimensional_tumbler.png|framed|center|Paul Callahan's unidimensional tumbler predecessor {{JavaRLE|unidimensionaltumbler}}]]

The following pattern, also due to Callahan, has 66 live cells and fits in a 149×1 bounding box, yet dies out completely after 233 generations. Additionally, it is interesting because each half produces two gliders and two [[lightweight spaceship]]s.
[[Image:Unidimensional_nothing.png|framed|center|Paul Callahan's unidimensional pattern that dies completely {{JavaRLE|unidimensionalnothing}}]]

The smallest one cell thick pattern to emit a [[glider]] contains 12 live cells and fits in a 15×1 bounding box.<ref>{{Cite web|url=http://infinitegrowth.wordpress.com/2009/04/02/unidimensional-patterns-2/|title=Unidimensional Patterns (2)|date=April 2, 2009|accessdate=May 27, 2009|publisher=Infinite Growth Weblog}}</ref> It runs for 3183 generations before stabilizing and has a final population of 1059 cells.
[[Image:Unidimensional_six_gliders.png|framed|center|A unidimensional pattern that emits six gliders {{JavaRLE|unidimensionalsixgliders|brief}}]]

On October 11, {{year|2018}}, [[carybe]] found a 256×1 soup using [[apgsearch]] which produces a [[middleweight Schick engine]] along with some junk.<ref name="post64642" />

{{EmbedViewer
|pname = 1x256schickengine
|position = center
|caption = A reduced version (63×1) of the one-cell-thick [[Schick engine]] soup 
}}

==Spaceships and oscillators==
It is unknown whether or not there exists a [[spaceship]] that is one cell thick in one of its [[phase]]s, (research has been conducted in finding such a spaceship<ref name="post27410" />) though it can be shown via symmetry arguments that any such spaceship, if they exist, would have to move in the direction that it "points". The [[blinker]] is the only known ''finite'' [[oscillator]] that is one cell thick in one or more of its phases (tiling the plane with oooooo.. gives an infinite period-9 oscillator based on the [[worker bee]]), and in April {{year|1992}}, [[Allan Wechsler]] used a search program to show that there are no oscillators of period 3, 5 or 7 that are one cell thick. The situation is unknown for other periods.<ref>E-mail sent from Allan Wechsler to LifeList</ref> However, the [[pentadecathlon]] has a simple one cell thick predecessor, and the oscillator's evolution sequence involves it evolving into a pattern that evolves very similar to a one cell thick pattern.

A plausible strategy for building such unidimensional oscillators/spaceships is to create a synthesisable unidimensional pattern that is a predecessor to a [[universal constructor]]. Creating a unidimensional constructor predecessor is the easy part; synthesising it is much more difficult, as all sparks must disappear before it enters its unidimensional phase.

==One cell thick patterns evolving into one thick cell patterns==
A weaker problem is to find a unidimensional pattern that is the predecessor of another non-trivial unidimensional pattern. Non-trivial means that it must contain at least one line that is not the [[blinker]], a [[spark]], or a hypothetical one-cell-thick spaceship. For example, this rules out the pattern oo.o.oo.ooo, which becomes a single blinker without any of the separate line segments ever having the opportunity to interact. By contrast, the pattern ooooo.ooo also produces a single blinker, but the interaction between the two segments makes it a non-trivial unidimensional pattern.

Toroidalet presented a unidimensional predecessor of a unidimensional pattern in August 2016;<ref name="post33987" /> it evolves into a different one cell thick pattern in generation 9, and into two [[beehive]]s in generation 22:

{{EmbedViewer

|rle =
x = 48, y = 1, rule = B3/S23
3ob6o3b6o2b6o2b6o3b6ob3o!
}}

A different example was given by M. I. Wright in August 2017,<ref name="post49477" /> based on a suitable reaction identified by [[Wojowu]] in January 2012;<ref name="post5939" /> their pattern evolves into different one-cell thick pattern (albeit on a different axis) in generation 128, and subsequently into two [[traffic light]]s in generation 148:

Talk:List of common oscillators

Moonsheep: Fix my signatures.

== Period on this page? ==
I'm thinking we might as well add a column to this page that shows the period of each oscillator listed (and similarly on the [[list of common still lifes]] we should add a column with the number of cells in the pattern) for easy reference. Thoughts? [[User:Nathaniel|Nathaniel]] 00:13, 6 February 2009 (UTC)

: That makes sense. Maybe even one for period, one for number of cells on this page? There's still a lot of space on my screen (and also, one would think that both are sort of related to frequency of occurrence). [[User:Elithrion|Elithrion]] 00:44, 6 February 2009 (UTC)

:: Kk, I've added period. I'll add cells later when I add cells to the other list. [[User:Nathaniel|Nathaniel]] 00:52, 6 February 2009 (UTC)

:: I've added an entry and a column for [[heat]], and added an "h=" option to the oscillator template so that the infobox on oscillator pages can display the heat of that oscillator. I'll start adding cell counts now. One thing I wanted input on though: currently none of the period numbers in the table are links... should the first occurrence of each period in the table link to that category? (eg. should the "3" beside pulsar in the table link to the category of oscillators with period 3?) [[User:Nathaniel|Nathaniel]] 03:41, 6 February 2009 (UTC)

::: Hmm... well, more links are almost never a bad thing, so sure! On a side note, heat on its own seems almost pointless - I know the pulsar is really hot because it's really big. Heat per cell or something like that would be a better measure. Although, that said, I guess having a heat column and a cells column almost removes that problem. [[User:Elithrion|Elithrion]] 03:49, 6 February 2009 (UTC)

:::: I agree with your comment about heat by itself being a silly measure. I'm reluctant to change it though because it seems as though heat is what's used commonly, and as you said, with cells listed there as well it's not a huge issue. [[User:Nathaniel|Nathaniel]] 04:08, 6 February 2009 (UTC)

==Names==
So, umm... can we call [http://wwwhomes.uni-bielefeld.de/achim/icons/gol/17_614.gif this one] "[[Test tube baby]] and [[tub]]" (or maybe "with tub" or "in tub", heh). That's basically what it is, and I doubt that anyone out there has a different name coined for it anyway. [[User:Elithrion|Elithrion]] 05:18, 6 February 2009 (UTC)

: Yeah I was going to suggest that we pick a name for that one as well (I was going to suggest "odd test tube baby" in analogy to [[short keys]], [[bent keys]], and [[odd keys]], but I'm perfectly happy with either name, or even putting one as an alternate name on the page). [[User:Nathaniel|Nathaniel]] 05:25, 6 February 2009 (UTC)

:: I think I like yours better, not least because I didn't really notice thee tub/non-tub distinction at first. Ah, paying attention, I should try it some time... [[User:Elithrion|Elithrion]] 05:56, 6 February 2009 (UTC)

::: Kk, I've added that page now. [[User:Nathaniel|Nathaniel]] 13:51, 6 February 2009 (UTC)

== By rotor version ==

I started one here: [[List of common oscillators/By rotor]]

Still needs summing of frequencies (and perhaps a renumeration of ranking), but preliminarly, three things stand out:
* Orthogonal on-off variants altogether seem to be almost as frequent as figure 8; taken to infinity, it may or may not overtake it.
* Queen bees altogether are more common than mazing, blocker, and jam, probably also more common than tripole (but that one could have further) (And yes, I'm aware the ''cis''-QB and ''trans''-QB have technically different rotors.)
* Phoenix and hook-eating-tub variants are giving tumbler a run for its money; I would bet on their order to reverse in the long run as more soup data is accounted, since a griddle w/loaf should probably be about as common as the boat variant…
--[[User:Tropylium|Tropylium]] 02:21, 3 June 2011 (CDT)

: A larger census was done a while ago which had much higher frequencies and for a larger amount of oscillators. [http://soakerhoo.110mb.com/lf020n.pdf Here] is a backup of it, the original was lost when Geocities closed. It has similar problems with the data (no way of differentiating between cis and trans-QB's, or telling 2 eaters from the p3 [[Two eaters]]).Maybe this could be used to make a more accurate version of the table? [[User:Lewis|Lewis]] 07:54, 8 June 2011 (CDT)
::Probably. I'll leave starting that for someone who knows how to auto-filter still lifes out of the list, tho… 1600+ pages is a bit long to work thru manually. :B --[[User:Tropylium|Tropylium]] 17:20, 19 June 2011 (CDT)

== Make the table sortable ==
I understand that the point of this table is to display the most common oscillators in their commonness order. Wouldn't it be nice though if the table was sortable such that you could quickly find, for example, common high-heat oscillators?
[[User:Moonsheep|Moonsheep]] ([[User talk:Moonsheep|talk]]) 19:09, 15 October 2021 (UTC)
: I've made the change and it is very simple. However, note that the system does not recognize those powers of 10 and thus the last column of frequency is not sorted properly. [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 17:26, 15 October 2021 (UTC)
:: Nice! I don't think the powers of ten should be a problem; you can already sort by rank, which is correlated with the frequency anyway. Likewise, I think we should apply this to other "List of common _" pages. I was surprised to find there are actually [https://www.conwaylife.com/w/index.php?search=list+of+common quite a few of them].

List of common evolutionary sequences

2021-10-15T18:27:25Z

Moonsheep: Make table sortable

In late {{year|2016}}, [[Simon Ekström]] determined the most common [[evolution]]ary sequences using 8×8 random [[soup]]s.<ref name="post38773" />

To qualify on the list, a pattern must initially have 12 or fewer cells and reach 20, staying above 12 for at least four generations with different population, at some point in its evolution. For this reason, the [[traffic light]] and [[interchange]] do not qualify.

Other patterns of note that are more common than the switch engine include [[multum in parvo]] (3404), one of the less familiar fours, four blocks in a rectangle (1615), the sequence that forms from a row of 8 on cells (1434), a clean [[paperclip]] (1053), [[gliders by the dozen]] (855), and a clean [[bipond]] (830).

This census for small, common active regions may provide insights into finding bottlenecks for new [[conduit]]s.

List of common spaceships

2021-10-15T18:25:22Z

Moonsheep: Make table sortable

This is a '''list of the most [[common]] [[spaceship]]s''' in the [[Conway's Game of Life|Game of Life]], specifically [[Catagolue]]'s B3/S23/[[symmetry|C1]] census as of July 2019. The patterns in this table beyond row 4 are only approximately ranked, as they all occur very infrequently so it is difficult to generate accurate estimates of their occurrence. The minimum known [[glider synthesis]], as of April 2020, of each spaceship is also displayed. The '''approximate relative frequency''' column gives an estimate of the proportion of all randomly-occurring spaceships that will be of the given type.

List of common still lifes

Moonsheep: Make table sortable

This is a '''list of the most [[common]] [[still life|still lifes]]''' in the [[Conway's Game of Life|Game of Life]], specifically [[Catagolue]]'s B3/S23/[[symmetry|C1]] census. The minimum known [[glider synthesis]], as of October 2021, of each still life is also displayed. The "approximate relative frequency" column gives an estimate of the proportion of all randomly-occurring still lifes that will be of the given type.

This table only includes [[still life#Strict still lifes|strict]] still lifes and thus does not count objects like [[honey farm]]s.

Talk:List of common oscillators

Moonsheep:

== Period on this page? ==
I'm thinking we might as well add a column to this page that shows the period of each oscillator listed (and similarly on the [[list of common still lifes]] we should add a column with the number of cells in the pattern) for easy reference. Thoughts? [[User:Nathaniel|Nathaniel]] 00:13, 6 February 2009 (UTC)

: That makes sense. Maybe even one for period, one for number of cells on this page? There's still a lot of space on my screen (and also, one would think that both are sort of related to frequency of occurrence). [[User:Elithrion|Elithrion]] 00:44, 6 February 2009 (UTC)

:: Kk, I've added period. I'll add cells later when I add cells to the other list. [[User:Nathaniel|Nathaniel]] 00:52, 6 February 2009 (UTC)

:: I've added an entry and a column for [[heat]], and added an "h=" option to the oscillator template so that the infobox on oscillator pages can display the heat of that oscillator. I'll start adding cell counts now. One thing I wanted input on though: currently none of the period numbers in the table are links... should the first occurrence of each period in the table link to that category? (eg. should the "3" beside pulsar in the table link to the category of oscillators with period 3?) [[User:Nathaniel|Nathaniel]] 03:41, 6 February 2009 (UTC)

::: Hmm... well, more links are almost never a bad thing, so sure! On a side note, heat on its own seems almost pointless - I know the pulsar is really hot because it's really big. Heat per cell or something like that would be a better measure. Although, that said, I guess having a heat column and a cells column almost removes that problem. [[User:Elithrion|Elithrion]] 03:49, 6 February 2009 (UTC)

:::: I agree with your comment about heat by itself being a silly measure. I'm reluctant to change it though because it seems as though heat is what's used commonly, and as you said, with cells listed there as well it's not a huge issue. [[User:Nathaniel|Nathaniel]] 04:08, 6 February 2009 (UTC)

==Names==
So, umm... can we call [http://wwwhomes.uni-bielefeld.de/achim/icons/gol/17_614.gif this one] "[[Test tube baby]] and [[tub]]" (or maybe "with tub" or "in tub", heh). That's basically what it is, and I doubt that anyone out there has a different name coined for it anyway. [[User:Elithrion|Elithrion]] 05:18, 6 February 2009 (UTC)

: Yeah I was going to suggest that we pick a name for that one as well (I was going to suggest "odd test tube baby" in analogy to [[short keys]], [[bent keys]], and [[odd keys]], but I'm perfectly happy with either name, or even putting one as an alternate name on the page). [[User:Nathaniel|Nathaniel]] 05:25, 6 February 2009 (UTC)

:: I think I like yours better, not least because I didn't really notice thee tub/non-tub distinction at first. Ah, paying attention, I should try it some time... [[User:Elithrion|Elithrion]] 05:56, 6 February 2009 (UTC)

::: Kk, I've added that page now. [[User:Nathaniel|Nathaniel]] 13:51, 6 February 2009 (UTC)

== By rotor version ==

I started one here: [[List of common oscillators/By rotor]]

Still needs summing of frequencies (and perhaps a renumeration of ranking), but preliminarly, three things stand out:
* Orthogonal on-off variants altogether seem to be almost as frequent as figure 8; taken to infinity, it may or may not overtake it.
* Queen bees altogether are more common than mazing, blocker, and jam, probably also more common than tripole (but that one could have further) (And yes, I'm aware the ''cis''-QB and ''trans''-QB have technically different rotors.)
* Phoenix and hook-eating-tub variants are giving tumbler a run for its money; I would bet on their order to reverse in the long run as more soup data is accounted, since a griddle w/loaf should probably be about as common as the boat variant…
--[[User:Tropylium|Tropylium]] 02:21, 3 June 2011 (CDT)

: A larger census was done a while ago which had much higher frequencies and for a larger amount of oscillators. [http://soakerhoo.110mb.com/lf020n.pdf Here] is a backup of it, the original was lost when Geocities closed. It has similar problems with the data (no way of differentiating between cis and trans-QB's, or telling 2 eaters from the p3 [[Two eaters]]).Maybe this could be used to make a more accurate version of the table? [[User:Lewis|Lewis]] 07:54, 8 June 2011 (CDT)
::Probably. I'll leave starting that for someone who knows how to auto-filter still lifes out of the list, tho… 1600+ pages is a bit long to work thru manually. :B --[[User:Tropylium|Tropylium]] 17:20, 19 June 2011 (CDT)

== Make the table sortable ==
I understand that the point of this table is to display the most common oscillators in their commonness order. Wouldn't it be nice though if the table was sortable such that you could quickly find, for example, common high-heat oscillators?
--[[User:Moonsheep|Moonsheep]] 16:12, 15 October 2021
: I've made the change and it is very simple. However, note that the system does not recognize those powers of 10 and thus the last column of frequency is not sorted properly. [[User:GUYTU6J|GUYTU6J]] ([[User talk:GUYTU6J|talk]]) 17:26, 15 October 2021 (UTC)
:: Nice! I don't think the powers of ten should be a problem; you can already sort by rank, which is correlated with the frequency anyway. Likewise, I think we should apply this to other "List of common _" pages. I was surprised to find there are actually [https://www.conwaylife.com/w/index.php?search=list+of+common quite a few of them]. --[[User:Moonsheep|Moonsheep]] 18:20, 15 October 2021

{{for|the website named "Pentadecathlon"|Game of Life News}}
'''Pentadecathlon''' (or '''PD'''; plural '''pentadecathlons'''{{refn|group=note|The correct Ancient Greek dual and plural forms, ''pentadecathlo'' and ''pentadecathla'',<ref name="wiktionary" /> are not in common use.}}) is a {{period|15}} [[oscillator]] that was found in {{year|1970}} by [[John Conway]]<ref>{{CiteHickersonOscillators|accessdate=March 14, 2020}}</ref> while tracking the history of short rows of cells (see [[one-cell-thick pattern]]); indeed, an orthogonal row of 10 cells evolves into this object. It is the only known oscillator that is a [[polyomino]] in more than one [[phase]] (besides the [[blinker]]).

==[[List of common oscillators|Commonness]]==
Pentadecathlon is the most common natural [[oscillator]] of [[period]] greater than {{period|3|brief}} (and indeed, the second most common natural oscillator of period greater than 2) in [[Achim Flammenkamp's census]]. In fact, it is the fifth or sixth most [[common]] oscillator overall in this census, being about as frequent as the [[clock]], but much less frequent than the [[blinker]], [[toad]], [[beacon]] or [[pulsar]].<ref name="achim" /><ref name="soupsearch" /> It is also the most common oscillator with a [[volatility]] of 1. The pentadecathlon is also the fifty-second most common object on [[Adam P. Goucher]]'s [[Catagolue]] and by far the most common period 15 oscillator, with all other natural oscillators of that period featuring it combined with some other object.<ref name="statistics">{{citeCatagolueStats|September 22, 2020}}</ref>

The second-most common period-15 oscillator, {{LinkCatagolue|xp15_4r4y14r4z4r4y14r4|patternname=bi-pentadecathlon 1|style=raw}}, consists of two pentadecathlons placed next to each other so that their sparks cancel out. This oscillator first appeared [[natural]]ly in March {{year|2015}},<ref name="post17573" /> and the [[reaction]] which produced it later led to a {{gliders|7}} [[synthesis]] of a bi-pentadecathlon.<ref name="post24296" /> Additionally, a [[pulsar]]-on-pentadecathlon is the largest object to have occurred in the B3/S23/C1 census as of September 2020, with 100 cells in its maximum phase.<ref name="post18884" /><ref name="statistics" />

==Uses of the pentadecathlon==
The pentadecathlon is so called because it has a period of 15 generations. This, being a factor of 30, means that it can be elegantly used in combination with period 30 devices (based on the [[queen bee shuttle]]). Firstly, it can reflect a glider 180° as in [[p60 glider shuttle]], and a [[PD-pair reflector|pair of perpendicular pentadecathlons]] can rotate a glider 90° or 180° as in [[6 bits]] and [[106P135]].

==Hassling capabilities==
The pentadecathlon is classified as a '''pulsating''' oscillator, since it undulates throughout its cycle. During this process, the pentadecathlon throws off multiple accessible [[sparks]]. More specifically, the oscillator produces horizontal [[T-nose]] sparks and horizontal [[V spark]]s in the form of [[phi spark]]s, as well as vertical [[domino]] sparks. Two copies of these domino sparks can be used to [[hassle]] [[toad]]s in two distinct ways. The V sparks elegantly convert blocks into gliders, which forms the basis of the p30 [[xWSS]]-to-glider [[converter]] and aforementioned glider reflectors. This property is also exploited in numerous oscillators.

==Synthesis==
On April 11, {{year|1997}}, Heinrich Koenig found a three-glider collision that produced a clean pentadecathlon. This was a surprising result at the time. Four-glider pentadecathlon [[recipe]]s had been known and used for many years, so this was an unlooked-for improvement, very similar to Luka Okanishi's discovery of a three-glider synthesis of a [[switch engine]] almost twenty years later. This also makes the pentadecathlon the rarest object in [[Catagolue]] for which a 3-[[glider]] [[synthesis]] is known.

==Other rules==
*In [[EightLife]], it still functions as a period 15 oscillator, but it generates extra internal [[spark]]s.
