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 and bushing 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] and the 57th most common oscillator on Adam P. Goucher's Catagolue.
Glider synthesis
All strict still lifes with a population of 20 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
