LowDeath rule
Rulestring 238/368
B368/S238
Rule integer 137544
Character Chaotic
Black/white reversal B123478/S134678

LowDeath is a Life-like cellular automaton in which cells survive from one generation to the next if they have 2, 3 or 8 neighbours, and are born if they have 3, 6 or 8 neighbours.

Patterns

Many patterns from HighLife are compatible with this rule. HighLife's replicator works in this rule, albeit with a different evolution sequence due to the result of Pedestrian Life's pedestrian effect.

Universality

There is a proof sketch of LowDeaths's universality. It is on ConwayLife forums,[1] which contains a proof-scheme covering all rules in the outer-totalistic rulespace between B3/S23 and B3678/S23678.
