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

Occurrence

See also: List of common oscillators

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 bookend, approximately as common as the boat on spark coil, and more common than fore and back and xp2_8e1t2gozw23.[2] It is the 32nd most common oscillator on Adam P. Goucher's Catagolue.

It is the most common griddle oscillator, being about 5 1/2 times more common than second place, beehive on griddle.

Glider 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]
