Sorry for the doublepost.
Much smaller one, also by Sokwe:

Here is the new p3 catalyst by itself:

Here's a p5 version of the catalyst, not necessarily minimal:

Code: Select all

x = 18, y = 15, rule = B3/S23

p4 versions have a solution with tiny p4 rotors and p2 supports. Here's the one used in gun_80:

Code: Select all

x = 12, y = 11, rule = B3/S23

Here’s a different one, which was in the Discord but likely missed (Edit by Sokwe: the following is a p4 variant by Discord user :pink_heart: which was made obsolete by the p4 variant by Sokwe and Scorbie posted above):

Code: Select all

x = 13, y = 15, rule = B3/S23

A stator variant of the p3 B-to-G catalyst can act like the drifty eater 3 in some cases:

Code: Select all

x = 31, y = 11, rule = B3/S23

2b2o$2b2obobo9bo3bo3bo2bo$6b2o10b2o6b2o!

The same mechanism can probably work a different periods. It may be useful because of the quick recovery time.

The bumper can act as a periodic catalyst, and turn some non-glider objects or sparks into gliders:

Code: Select all

x = 42, y = 16, rule = B3/S23

Here are oscillators that can catalyze in the same way as toads for prime periods up to 13:

Also, two ways to use 38P5 as a catalyst:

P2 version that is smaller (sorry if already known):

Code: Select all

EDIT: Unfortunately, it cannot work with the functionally stable p8 reflector.

Glider catalyst??

Code: Select all

 x = 10, y = 7, rule = LifeHistory
8.2A$7.A.A$7.A$7.2A$A$.2A$2A!

which means glider loops can also be catalysts.
The glider catalyst seemed to be work on a specific frontend:(yellow cells must be on and red ones must not)

Code: Select all

 x = 7, y = 7, rule = LifeHistory
2.D2E2A$2.4DE$3.3E2$A.A$.2A$.A!

This P3 from a recent oscillator of mine can sometimes replace chucklebait:

Code: Select all

x = 35, y = 22, rule = B3/S23

o13bo$12b2o$7bo4b3o$3b2o3b2o5bo$3bo2bobo5b2o$5b2o2bo$8b2o!

It uses a known eater + dot spark reaction, but I don’t think a P3 oscillator that supports the reaction has been found until then.

Using keys is smaller, but has lower clearance:
