I don't think it is, nice find! That's also kind of hilarious that it is one cell above the best known.2718281828 wrote:Is this non-monotonic 123 cell c/6 cell ship known? I did not find it here or on related pages.

Nothing else than the mentioned ones. Gfind and ntzfind. Ntzfind for the c/6 ship (with restricted length), for the 2c/5 gfind.AforAmpere wrote:Nice. Which program are you using for these? ntzfind, gfind, or something else?

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 23.2718281828 wrote:I think, a plausible speed where we might find a ship is 2c/7 diagonal.
