Here's an odd interaction. These two catalysts are usually identical, but one of them is a bit more theatrical about how it recovers, which allows it to modify this particular input with a thumb-like protrusion on the right tick: x = 45, y = 20, rule = LifeBellman 6.5A25.5A$7.3A27.3A$8.A29.A2$8.2A28...

The observation that natural motifs are more likely to be catalysts is kind of profound, and IMO, could be the basis of another complex catalyst searcher.

EvinZL found a periodic HNW15T105 .

All but two cuphooks would likely be solved automatically if transfer.py worked on oscillators. Luckily, using the component that mniemiec pointed out, all but two of them can be converted from a still life into the relevant cuphook. It may be worth running transfer.py to take these still lifes apar...

I'd like a script that looks up all of the guns on Catagolue from period 15 through 999 and which are divisible by 3, and then returns the list of guns which both contain fewer than 10 cells that oscillate at period 3. This script is intended to find guns which have not yet applied p3 eaters.

Kazyan

There are still plenty of p3 eater replacements left to do in Catagolue's gun collection, and I'm making those changes as I find them. For example, here's the p741 gun shrunken by two columns: x = 88, y = 65, rule = LifeHistory 30.2A$29.A.A$23.2A4.A24.2A$21.A2.A2.2A.4A20.A.A$21.2A.A.A.A.A2.A22.A 4.2...

Given that it has now become reasonable to make bespoke oscillators for specific interactions, I've been giving some thought to the idea of a universal, low-period block keeper or blinker keeper. Such an oscillator would have a sparking area that is suppressed by a block or blinker, which, when remo...

When using CatForce, occasionally you'll get a loaf as a catalyst that creates a normally-unsalvageable Pi very close to itself.
