Commonness
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]
gollark: Yes.
gollark: To be fair, they weren't very effective at it.
gollark: <@&198138780132179968> Wyatt's reminded me that they have a house in Chorus City on one of their accounts (at 3974 48 -2829) and I was wondering what could be done with it, since they're banned (possibly permanently?).
gollark: Wait, what?
gollark: Cool Chorus City picture.
