Eater plug (or cavity[1]) is an extensible period 2 oscillator that was found in February 1973 by Robert Wainwright. Its name derives from its resemblance to two diagonally-touching eater 1s. It is about the fifty-fifth most common naturally-occurring oscillator.[2] (Curiously, the similar but slightly larger great on-off is over 1000 times more common, being the ninth-most common oscillator altogether.)
