## Counterfeit Gliders

For discussion of other cellular automata.

### Re: Counterfeit Gliders

Glider as a p100 oscillator:
x = 3, y = 3, rule = B2e3-a/S23

Random find in a search for small spaceships in B0 rules. Guess which way this goes.
x = 3, y = 3, rule = B012ik3-eijq4-iknr5-ajkr6-ae8/S1e2ak3-ack4-ceqwy5aknqy6e
bo\$2o\$obo!

Also, most patterns in this rule tend to, not entirely surprisingly, explode. However, if you start with a random seed like, say, the slightly tweaked "glider" below and let it run long enough (in this case, about 3000 generations), something curious happens to the expanding ball of chaos. I've seen other rules with this kind of behavior, but I'm not sure what to call it. Is there a name for it?

This rather stable puffer front-end forms and quickly escapes the rest of the chaos:
x = 5, y = 5, rule = B012ik3-eijq4-iknr5-ajkr6-ae8/S1e2ak3-ack4-ceqwy5aknqy6e
2bo\$bobo\$obo\$bob2o\$3b2o!

Since this rule is so chaotic, however, the "ball" and the puffer trail are permanently stuck together resulting in an unusual shape.

Indeed. The same thing happens e.g. in the totalistic von Neumann rule B04/S1V:
x = 5, y = 4, rule = B04/S1V
ob2o\$2bo2\$4bo!

Calling those things puffers doesn't really match the usual definition of the word, though, since their trail is neither stable nor periodic. It's not even clear if the engines themselves are truly stable, although they do seem like they are. (In fact, in some rules there are similar engines that are unstable, propagating for a while before eventually breaking down and getting swallowed by the chaos behind them.) It just seems like there ought to be a distinct term for these things.

How about "rocket"? Real-life rockets produce seemingly-random trails of smoke and travel a variety of distances before stopping.

Rocket usually refers to patterns that look like spaceships but die down, it was first used with Day&Night.

At least, I think so.

I would think so. The dot is a spark that reappears immediately only because the ship moves at c.
EDIT: Actually, no. See wwei23's post below.

No. The ship must share a phase with a phase of the glider with exactness. Extra dots are not welcome.

Glider to R and back:

Same idea, but fast:
x = 3, y = 3, rule = B2cn3-ekqr4ijqw5acejy6ack7/S2-cn3-aiq4ciw5i6ace7e

It can get even faster:

This rule is Arrow, by the way.

That rule is explosive due to a failed replicator, but adding S5i gives a non-explosive rule with the same counterfeit glider:
x = 3, y = 3, rule = B2e3eikny4aekrw5aikny6eik7/S1c2-ai3acky4aenqt5inry6-cn78
