I see that the P9 has an entry. Why not also add the P18 R-pentomino shuttle that A for Awesome and hotdogPi constructed with it? p18 That by itself may not be sufficient enough for an entry, but we could combine it with other hasslers, like this p84 one, in an entry: x = 73, y = 77, rule = B3/S23 ...

Congratulations! Funny how this resembles the scholar so much (p7, second elementary spaceship of the speed, discovered near the end of the year) To say something constructive, the spaceship can eat a glider in a very nontrivial way and there's probably some puffer engines as well: x = 51, y = 42, r...

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. No one responded, so I did it myself (the code is a lot messier than the asymmetric one at the ...

I recently got python 3.9 and 2.7.13 and when I tried to run apgsearch it came up with this error message: Don't know but you should be better off running the much faster 5.x version of apgsearch, considering you'll need to know how to use the terminal anyways if you want to use gfind (which is cur...

Yes, but along with Kazyan's recent c/61 orthogonal partial and a couple of other examples where a common object or arrangement of common objects happens to form from almost the same setup except translated or glide-reflected, it could suggest that looking for high-period spaceships where one phase...

According to Catagolue, this eight-bit constellation (composed of a boat and a blinker) costs nine gliders.

Yep, there's a lot of overly-expensive constellations on Catagolue, which are usually caused by failed synthesis steps.
Also see this.
