### Re: Spaceships in Life-like cellular automata

I found that Rocknlol had found a c/5o earlier in B378/S2458 (here), so I took out a few entries made redundant by it.

Code: Select all

#C Rocknlol, 2020, B37/S245-B378/S24578
x = 14, y = 22, rule = B37/S245

They are:

A user named eran911 found a (14,9)c/165 puffer in B368/S237 and wonders if it could be corderized. It is: Code: Select all x = 19, y = 22, rule = B368/S237 13bo$12bobo$12bobo$13bo$8b2o6b3o$8b2o3$16bo$15bob2o$13bo4bo$o5b2o5bo4b

A (4,2)c/44 wickstretcher in B36/S24567 is also mentioned, but a spaceship at that speed is unlikely to exist. I'm interested in seeing if we could find more like them. More recently, AforAmpere and I found a strong (2,1)c/7 partial in B36/S23. I was going to search the next width (margin 15) in LSSS, but got sidelined by other searches like the c/4o one I'm currently running in Seeds.

Ikpx's source code specifies CGoL exactly once, but an attempt to adapt it to other rules ran into a roadblock. Details here.

EDIT: More partials, all found by Sokwe in 2010 (see here):

I'm not sure what you've already looked through. The obvious thing is to search through each of the Life-like threads and check any posted spaceships against those in the database. The other thing to do is use the advanced search feature to find all posts by Josh Ball (Velcrorex) in the Other Cellular Automata board. Most of them will contain spaceships or discussions of spaceships. For example, this post by Josh Ball contains a 2c/5 ship not currently found in the database. There are probably a handful of additional spaceships in the Thread for Your Accidental Discoveries that Aren't in CGOL and Miscellaneous Discoveries in Other Cellular Automata. Also, Glider 21575 was found by Nicolay Beluchenko, not Artem Dergachev. See this post.

Of all the rules I would think might have spaceships, B3457/S1238 would not be one of them. Random patterns in that rule expand quickly with blotchy internal chaos. 2c/4 ships are often the easiest ships to find in such rules. That particular ship was the only thing found in my width-8 2c/4 sweep of B3 rules without any known ships. I have been examining a few rules with B3456 and without any of S123. Such rules often favor odd-period ships with displacement 1. I recently found c/7 ships in B3456/S45 and B345678/S47. It turns out, they also have relatively small c/9 and c/11 ships: Code: Select all x = 33, y = 142, rule = B3456/S45 26b4o$24bo2b2o2bo2$24b8o$25b6o$24b8o$25b6o$24b2ob2ob2o2$24b3o2b3o$26b 4o$24b3o2b3o$25b6o$24bobo2bobo$25b2o2b2o$24bobo2bobo$25b6o$24bo2b2o2bo

### Re: Spaceships in Life-like cellular automata

I've decided to dedicate this week to finding p5 knightships with LSSS. I've noticed that four of the eight known p5 knightships (B3678/S34678, B3/S1346, B3/S0346, and B357/S346) are in rules of the form B3xx/S[01]346yy, so I have chosen to focus there. Here's a strong partial result from one search:

Aside from those, I found that some rules near B36/S235 have very strong p5 knightship partials. For example, other than B36/S235 itself, I found the following partial:

Code: Select all

x = 29, y = 9, rule = B36/S0235
2bo24b2o$b2o16bo4b3obo$4o9b2ob3obob2ob2obo$4b2o3b7o3bo2b3o2b2o$2bo4bo
2b3obob2o5bo4bo$4b2o6bo2bo3bob5o$9bobo2bo4bobo2b4o$15bo2b2obo5bo$28bo!

An exhaustive search in 2013 using Paul Tooke's mod for gfind found that the p5 knighship in B3578/S235[8] is the only one up to width 10. No other general bounds are known. Maybe try exhaustively searching the B3 rules up to some higher width?

Code: Select all

x = 4, y = 3, rule = B3-q4z5y/S234k5j

Now I really want ntafind. Is it available anywhere or is it the "no-one-bothered-to-modify-it" case?
