`x = 8, y = 8, rule = LifeHistory`

The goal is to find the smallest still-life (or constellation of them) that stabilizes all of the cells. IN this particular case, I believe the smallest stabilization is this, with 23 total cells:

`x = 8, y = 9, rule = LifeHistory`

2.AC.CA$.C.A.C$C2.C.C$CA2.A2$6.2C$3.AC2.C$2.C2.2A$2.2A!

Answers will be ranked by the cell count of the stabilized constellation. As a first challenge, try this:

`x = 16, y = 10, rule = LifeHistory`
