Quite far, we're missing periods 7, 9, 10, 11, 13-16, 18, 19, and 21 (at least according to Catagolue), though when higher symmetries are apgsearched some of those gaps will inevitably be filled in.

Do we really meed like 90% of the ship just to correct one misplaced cell on each side? That honestly seems a bit excessive. I agree.

I actually can't believe you if you're reading this text. So I guess you noticed there was an awkwardly large gap between the previous line and the signature, or did you just highlight stuff at random? This is awkward. Bye.

SilverMirrorLife was discussed a bit on the discord as it adds a common 2c/6 ship; here's a variant of it which also has a 3c/21 diagonal ship and a 15c/49 orthogonal ship based on a failed replicator: x = 52, y = 7, rule = B3-kq4j5r67/S2-i34q6ak7c bo20b2o25bo$3o18b2o25bobo$obo17b2o25b2ob2o$3o17bo26...

Check out Space Invaders. It's an explosive, yet apgsearchable rule. Even the rule with B4e added (which tames it significantly without removing its dynamics) doesn't look apgsearchable in C1, though D4_+4 worked for me.

Question (previously asked on discord but I think they were busy): Could anyone modify the script to produce only collisions with D2 (+1, +2, x) symmetry? I think we'll find some more improvements there.

Yeah, the synthesis was kind of rushed so I didn't bother optimizing. Any table on table to hat converters to transform it to the canonical version?

A bunch of oddities I can explain some of these: Oddity 1: Catagolue doesn't check if linear growth apgcodes are actually valid since (as far as I know) they are based on population changes and not what the pattern actually is: http://catagolue.hatsya.com/object/yl5_thisislineargrowth/b3s23 Oddity ...

Is this one OK?

Yes but it's a lot slower and the python versions have fallen into disuse.
Alternatively there's the Catagolue tutorial if you still need help with the command line versions.
