Here's B2in34-rz5er6ei/S2-cn3-a4ik, one of those longlived OWSS rules, but that doesn't seem to have that spacefiller or any single-engine puffers like some of the others. 5c/30 spaceship: x = 4, y = 5, rule = B2in34-rz5er6ei/S2-cn3-a4ik 3bo$o2bo$o2bo$o2bo$3bo!

I think this huge XWSS rule always either stabilizes into a puffer, or the spacefiller if nothing's around:

413781-generation methuselah in a rule with S4i engines, but ones that seem to turn into pairs of c/2 spaceships or a low period puffer: x = 3, y = 8, rule = B3/S23-n4-ajrwy b2o$2bo$b2o2$b2o$2bo$3o$o!

Galaxy S10 here, LifeViewer works fine for me.

I want to make some rules with creative definitions. Here is B345678/S2456, but all live cells involved have to form a polyomino: B3ai4a5ai6a78/S2aei4-cknqy5-ejk6-e. It sort of reminds me of a deader version of Move. There is a failed replicator that travels at 7c/25, but it can be made into a true ...

Would this 5-cell pattern count? Around 160000 generations it spawns a puffer to the right, but I don't know if it stabilizes.

That's actually a growing breeder! This is nice This failed replicator copies itself in really strange ways, producing puffers: x = 3, y = 3, rule = B3/S2cen34aiknrwz5acein 2o$3o$2o!

Is "betweening" B4 or S4 off the table, since they have an odd number of transitions? (13) EDIT: I'm making this post constructive. Spaces involving B3/S345 seem interesting.

On switch engine ping-pong, it currently states:

and it shows that quadratic growth can be synthesized with no more than 7 gliders.

In 2022*, quadratic growth was synthesized using 6 gliders*, so it should be phrased in a way that acknowledges that 7 is no longer the minimum

That ship was actually found by qqd, I just found an eater for it.

Ships galore (known c/2o, c/4o, glider, c/8o and c/9o): Interestingly, A boat can eat all except the c/9: x = 35, y = 10, rule = B3/S23-a4-aeikn5y6cn7e8 bo$2bo$3o2$18b2o12b2o$17b3o4b5o2bo2bo$18b2o3bo7b3o$5bo18b2o7bo$4bobo 17b2o$4b2o!

why exactly are many people (it's not just dbell) reluctant to set up an account on Discord, just to be able to follow links such as these and get access to the details of the discussion? Well, one thing about putting things on the wiki instead of Discord is that as time goes on, it will be harder ...

Could the proof of p3-p25 phoenix nonexistence be crossposted or summarized on the forums or wiki? It seems kind of important and I do not use discord. I'm curious how they were ruled out.

It kind of surprises me that triple pseudo still life and quad pseudo still life don't seem to have syntheses in sjk. It looks a little difficult, but I bet a converter-based synthesis is possible.
