Pentoad
Pentoad (or eater-bound Z-hexomino[1]) is a period-5 oscillator that was found by Bill Gosper in June 1977. It consists of a Z-hexomino that is stabilized by two eater 1s.

It was discovered by Scott Kim that this oscillator is extensible by moving one of the eaters diagonally away by four cells and inserting another Z-hexomino in the gap.[2] A pentoad constructed in this way with n Z-hexominoes has 14 + 6n cells and heat 8.8 + 6.4n. The pentoad with two Z-hexominoes is shown below.

gollark: No, it's on-CPU, not the chipset.
gollark: It is, at least, not used as part of some commercially sold remote management product like Intel's ME is, as far as I know.
gollark: Does it? I thought it ran with basically the same "literally everything" perms as the Intel ME.
gollark: Bad?
gollark: Apparently Intel might have to outsource some of their GPU stuff, since their 7nm node is seemingly very behind schedule and they had contracts for providing some to a supercomputer project.
