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.

Here's hoping for a c/7543 or c/8654 ship. Bored of using the Moore neighbourhood for everything? Introducing the Range-2 von Neumann isotropic non-totalistic rulespace!

Re: The hunt for another B3457/S4568 ship

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

Code: Select all

x = 16, y = 8, rule = B3457/S4568
7b2o2$5b6o$3b10o$3b3ob2ob3o$b14o$3obobo2bobob3o$3ob8ob3o!

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

Code: Select all

x = 18, y = 19, rule = B3457/S4568
8b2o2$6b6o2$4b2obo2bob2o$3bo10bo$2b3obo4bob3o$2bobo8bobo$2o2b10o2b2o$3bo10bo$6ob4ob6o$bob3o6b3obo$o3b10o3bo$b6o4b6o$ob4ob4ob4obo$b6o4b6o$6o

Heres the final result, with 0 spaceships found:
