Griddle and block (or singular flip flop) is a period 2 oscillator that was discovered by Robert Wainwright in July 1972.
Griddle and block is about the thirty-sixth most common naturally-occurring oscillator in Achim Flammenkamp's census, being slightly less common than the cis-beacon down and long hook, approximately as common as the boat on spark coil, and more common than fore and back and 21P2.[1]
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.[2]
