Re: One Glider Seeds

If the seed does turn out to be constructible with slsparse, then I think that implies demonoids and orthogonoids with speeds arbitrarily close to c/5 and (1,1)c/5 respectively. For that purpose, here's a simple way of stopping a 58P5H1V1 with a glider: x = 23, y = 23, rule = B3/S23 b2o$b2o$o2bo$o2...

Re: Spaceship Eaters

A glider output can be liberated from the H-to-pi conduit, so this is a converter rather than just a brain eater... There seems to be some potential for getting the repeat time down to 623, except I keep needing more and more extra stages, and some of them end up way too slow: I fixed the boat stag...

It's worth remarking that xs20 is the last size such that Catagolue can store the full tabulation of synthesis costs within the per-entity limit of 1 MB (and this is with compression; without compression, the limit would have been xs19).
