would you guys agree that this spaceship needs a name? Perhaps rocket?

I don't really think it's necessary for it to have a name- considering it is quite common in other rules as well. But if you want to name it, we could perhaps call it "Wanderer" as a tribute to the name of the rule it's in "Travelling T's". Feel free to call it your own nickname though!

Also welcome! I've noticed you joined the forums quite recently, I hope you like the community around and enjoy your stay friend!

To make it easier to keep track of oscillator periods, I've made a Catagolue census to which you can upload literally anything from this rule.

To make it easier to keep track of oscillator periods, I've made a Catagolue census to which you can upload literally anything from this rule.

How?

[PK22]

If your question is 'How do I upload to the census?', see Tutorials/Catagolue stdin symmetry.
If your question is 'How does this help to keep track of oscillator periods?', the xp categories show what periods have been uploaded.

How are the results in Catagolue sorted?

[PK22]

Like in any other census - first into the category of pattern (still life, oscillator, spaceship, linear growth, etc), and then into subcategories, usually by period or number of cells. If you check the the census, you can see the categories.

A Catagolue census is useful here since it shows the oscillator periods uploaded, so we can keep track of what periods from 1-100 are known.
Speaking of which, I would appreciate some help with getting the reflector loops for periods <100 built and uploaded, as well as any missing LCM oscillators - there has been a lot of searching on D8_1 and D8_4 (thanks to LuveelVoom and me), so there may be new sparkers.

Also, I love to see the enthusiasm - I said to upload 'literally anything', and someone did exactly that.

EDIT: One of the things we are missing is an accessible p9 sparker - I cannot find any p18 oscillators since all semi-natural p9s have D8_1 symmetry, leaving no space to squeeze a p2 or p6 to catch the internal sparks.

If you clone qfind in the same directory as apgsearch, and pipe the output of an apgsearch, compiled for b3s23-a5/Travelling_Ts_Collections_stdin, then it will upload ships directly to the symmetry, with no need for moving text files and copying ships.
For example: three c/5o's, uploaded directly to the symmetry:

Code: Select all

x = 13, y = 15, rule = B3/S23-a5

Edit: all c/4o ships below width 6 are certainly in the symmetry.

[PK22]

How exactly do I pipe the output? What commands do I need to run?
EDIT: Nevermind, figured out how.

[hibiscus]

Once qfind is compiled, and is in the same directory as apgmera, you can use a line of the following format:

Code: Select all

./qfind -r B3/S23-a5 -v 1 -w 2 -s a -t 3 | ./../apgluxe -n 4 -k [key]

where [key] is your own payosha256 key.

How many extendable oscillators have been found that give an infinite number of periods?

[PK22]

I got it to work, and I found this very small tagalong for a T that has not even been found by ikpx2:

Code: Select all

Note to anyone doing similar searches: the haul size grows very fast - I did a search for c/3 spaceships, but even 2214 soups exceeded the 1500 KB uncompressed limit.

EDIT:

As far as I am aware, extendable T loops make it possible to construct oscillators of periods 30+6n, 28+7n, 33+11n, 40+20n, and 32n. There are also period 32+16n and 8+16n loops based on 180 degree reflectors:

I would also check the iC1 census, just in case any Margolus oscillator periods have been missed.

There are currently 38/100 periods (if including still lives as period 1) from 1-100 in the Catagolue collection, but we can probably get that to 50/100 by filling in some of the missing periods with reflector loops.

1). No, but collecting them all in one census makes it fairly easy to go through manually and find a pattern with the property you want.
2). I doubt it - you need to phase-shift one of the gliders one time more than the other, but since both of them will use the same number of reflectors, this is difficult. The 180 degree reflection mechanism I showed does not put the T on the right lane.

[ThePlayzr]

For the 2 small c/2 spaceships, the smaller one may be labelled rocket, if Resu agrees with this name, but for now, refer to them as 7P2H1V0 and 10P2H1V0.
Also, Resu, could you please add a collection of smallest spaceships by population? Spaceships are normally sorted by population, as that is how they do it in CGoL, and bounding box is only used as a tiebreaker. We can still keep the bounding box collection, but we need a population collection. To help you, here is a link to the smallest c/3 spaceship by population: https://catagolue.hatsya.com/object/xq3 ... f/b3s23-a5.
We have achieved three large reductions of the smallest spaceships by population, we have reduced c/3 from 217 to 101, c/5 from 82 to 58, and now 2c/5 from 272 to 229! Keep up the good work team!

[mmmmmmmmm]

Note to anyone doing similar searches: the haul size grows very fast - I did a search for c/3 spaceships, but even 2214 soups exceeded the 1500 KB uncompressed limit.

Is there a way to limit the population of spaceships when you do that, perhaps by deleting ones over a certain population?

How many extendable oscillators have been found that give an infinite number of periods?

As far as I am aware, extendable T loops make it possible to construct oscillators of periods 30+6n, 28+7n, 33+11n, 40+20n, and 32n. There are also period 32+16n and 8+16n loops based on 180 degree reflectors

You can actually make a p16 using 180-degree reflectors, so it's 16+16n.

For example: three c/5o's, uploaded directly to the symmetry:

Code: Select all

x = 18, y = 15, rule = B3/S23-a5
4bo$2bo2b2o$b3ob2o6b3o$o3bobo4b6o$4ob3o2b2o2b3o$o2bo5bo7bo$b2o6b9o2$b2o6b9o$o
2bo5bo7bo$4ob3o2b2o2b3o$o3bobo4b6o$b3ob2o6b3o$2bo2b2o$4bo!

This is very sparky, it can perturb Ts, or turn them into a tub or pond, and can perturb 7P2H1V0, or turn it into 2 blinkers. I haven't tested fully though.

It seems like Blockic in CGOL is boatic in Travelling Ts (TTs?):

I’m not sure if “Boatic” is equivalent to Blockic here - in fact, I doubt an equivalent exists. The loaf is the most common still life, and almost twice as common as the boat. The loaf can serve as a one time 90 degree turner, which I don’t think the boat can do. The loaf is larger, however. I doubt that we can build one glider/T seeds using only one kind of still life.

“Spartan”, on the other hand, mostly retains its meaning here. I would argue that here, the loaf, boat, beehive, tub, pond, ship, and eater 1 are Spartan, and if necessary, the small lake, honeycomb, and hat siamese hat. We should be able to build splitters and one spaceship seeds using these still lifes only.

Even though we do not even have a gun yet, I think it is worth considering how universal construction would work in this rule. Slow salvos of either spaceship might be sufficient, or if not, we can try to use two perpendicular slow salvos. We will need spaceship duplicators in order to attempt either of these, however.
