Caterer on figure eight is a period-24 oscillator composed of a caterer and a figure eight. In terms of its 24 cells, it is the smallest known period 24 oscillator.[1]

Despite being composed of two oscillators of smaller period (3 and 8 respectively), it is considered non-trivial because it has a single cell that is alive in generation 23 and is dead in its other 23 phases.

gollark: And doesn't skip basically all the frames like that one does!

gollark: It has audio!

gollark: I have a Shrek WebM file which uses AV1 and ~~codec2~~ Opus to make an actually slightly watchable Shrek in 8MiB.

gollark: There is that one Shrek GIF floating around.

gollark: Also JPEG-XL.
