Block on griddle (or singular flip flop) is a period-2 oscillator that was discovered by Robert Wainwright in July 1972.[1]

Block on griddle is about the thirty-sixth most common naturally-occurring oscillator in Achim Flammenkamp's census, being slightly less common than the cis-beacon down on long hook, approximately as common as the boat on spark coil, and more common than fore and back and 21P2.[2]

Synthesis

In October 2014, Ivan Fomichev found a 6-glider synthesis for this pattern based on a soup from Adam P. Goucher's apgsearch script.[3] A 5-glider synthesis was found in July 2020.[4]
