The blinker is the smallest and most common oscillator, found by John Conway in March 1970. It is one of only a handful of known oscillators that is a polyomino, and it is the only known oscillator that is one cell thick (although the pentadecathlon is "almost" one cell thick in that there is a one cell thick pattern that is a grandparent of it).
Commonness
The blinker is more than one hundred times as frequently-occurring in Achim Flammenkamp's census as the second most common oscillator, the toad.[1]
