The hunt for another B3457/S4568 ship

B3457/S4568 is known for it's terribly slow c/5648, the slowest orthogonal elementary ship known. But are there other ships out there? Who knows? I have done ntzfind from p2 to p10, w6 to w8, currently doing p10 w7.

This is an outer-totalistic rule, so you can just use normal zfind. I hope that helps at the higher widths.

These types of rules interest me. I'm currently trying to hunt for the slowest ship by using blob rules. Wish me luck.

I find it interestingly coincidental that the speed of the spaceship is an anagram of the survival conditions.


Here's hoping for a c/7543 or c/8654 ship.

I strongly suggest a c/7 diagonal bilateral symmetric search, since we have this (promising) partial:

A really, really, really, really, really, really bad c/4 partial from zfind:

A considerably much better (but not as much as the one above) c/7:
