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: Monad transformers are weird. They basically reinvented imperative programming on top of functional programming.

gollark: Yes, as long as it doesn't use too much network bandwidth.
gollark: Yes, patching accursed JS web services from my phone is really what I want to do now.
gollark: Oh dear.
