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).
Blinkers are very commonly formed in a set of four called the traffic light; they can similarly be born in two potential sets of six, the interchanges. There is also a fairly common constellation of four blinkers and two boat-ties.
The blinker is more than one hundred times as common in Achim Flammenkamp's census as the second most common oscillator, the toad.[1] The blinker is also the second most common object on Adam P. Goucher's Catagolue.[2]
