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 diagonallytouching eater 1s.
It has an identical rotor to the great onoff, which is interestingly over 1000 times more common than it despite its size.
Commonness
Eater plug is about the fiftyfifth most common naturallyoccurring oscillator in Achim Flammenkamp's census.^{[2]}
