Is this non-monotonic 123 cell c/6 cell ship known? I did not find it here or on related pages.

It is slightly larger (1 cell) than the smallest currently known c/6 ship.

I don't think it is, nice find! That's also kind of hilarious that it is one cell above the best known.

Yes. But this c/6:

Nice. Which program are you using for these? ntzfind, gfind, or something else?

Nice. Which program are you using for these? ntzfind, gfind, or something else?

Nothing else than the mentioned ones. Gfind and ntzfind. Ntzfind for the c/6 ship (with restricted length), for the 2c/5 gfind.

Maybe for the record: Another 2c/5 and a relatively small asymmetric c/3 (still a bit larger than the symmetric record holder).

I think, a plausible speed where we might find a ship is 2c/7 diagonal.

[praosylen]

I think, a plausible speed where we might find a ship is 2c/7 diagonal.

Funnily enough, I've already been running a width-19 bilaterally symmetric 2c/7d gfind search for a few CPU hours now (but I started it well before you posted). I'll post if it finds anything, but I'd imagine ships probably don't exist until width 21 or 23.

EDIT: I was correct in my guess — there are no bilaterally-symmetric ships at width 19. Gfind output:

Unfortunately, I did not think to keep the longest partial. If anyone else wants to run the width-21 and/or 23 searches, feel free — it seems like they might be worthwhile, but I don't have the patience or the CPU time to spare at the moment.

Just call it a "wickpuffer".
I will call it a "wickpuffer", since I can`t find a pattern of the oscillating "noise", which might be simulating a dirty puffer in a 1dimensional CA (i dunno)
Can anyone prove that this is aperiodic or not?
