I'm guessing that two of the the bi-loaf 2 soups were rotations of this:

Code: Select all

x = 5, y = 5, rule = B3/S23
3o$2o$o3bo$3b2o$2b3o!

and that the switch engine came from this (from here):

Sorry to bump a really old topic, but this seemed the best place to post this. When I run a search using gfind, the output only gives (at most) one ship for each period/speed, and often it's not even of the full period (eg. it will output a c/2 p2 ship when searching speed 3c/6). When I search B3/S2...

Haven't got one with two perpendicular gliders, but I haven't done an exhaustive search so there could be one out there.

Does the wick-stretcher have a simple synthesis? As far as I know, there hasn't really been much investigation into synthesis of anything in this rule. With a bit of trial and error I found a few syntheses a while back of common natural objects, eg. here's the P26 from 3 'gliders' (probably the rar...

Would it be possible for the Catagolue site to give an option to display pages with static images instead? Any page with more than about ten SVG images on it loads really slowly, and trying to open one of the pages for individual hauls in 2x2 is causing my browser to freeze completely.
