Butter is an oscillator first discovered by Entity Valkyrie in 2019.

It only requires the corner dot spark, so molds can be in either orientatiion singly and doubly trans isomers.

Occurrence

Being glide-symmetric with a minpop of 38, it is not conducive to soup searches, and has not occurred in any censuses.

Synthesis

A final step for all three variants (creating the supporting molds from long boats while converting a mold with a single glider) was found by Goldtiger997 two days after its discovery.

In other rules

The B3a transition can also be omitted rather than suppressed, allowing unsupported butters but preventing mold and jam.
