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: random.org won't just let you say "hi I'm this IP".
gollark: What? It won't, though.
gollark: And the quota is presumably per-IP.
gollark: Because they are.
gollark: I mean, *random.org* will see the requests as coming from your friend's server.
