Eater plug

Eater plug (or cavity[1]) is an extensible period-2 oscillator that was found in February 1973 by Robert Wainwright.[2] Its name derives from its resemblance to two diagonally-touching eater 1s.

It has an identical rotor to the great on-off, which is interestingly over 1000 times more common than it despite its size.

Commonness

Eater plug is about the fifty-fifth most common naturally-occurring oscillator in Achim Flammenkamp's census.[3]

gollark: I can mostly only think of food and water as immediately problematic things, and it's still a lot easier to import help when on the ground.
gollark: Terrestrial housing gets breathable air and some degree of temperature control "for free".
gollark: It'll probably be a while before there are actually space habitats that big, and more having to be done technologically probably means more failures.
gollark: If they fail on a space habitat, I probably die horribly and can't easily get help from somewhere nearby.
gollark: If the power or water supply fail here, I'll probably be somewhat uncomfortable until they're restored, but be basically fine, at least as long as they're available somewhere not too far away.
