`x = 1, y = 1, rule = B1357/S1357`

o!

Or just program it for a rule similar to B123/S12345678, and you get the replication without the XOR weirdness where the population keeps dropping back down to 4 or 8 or 9, at increasing intervals.

The metacell's ability to function as (various kinds of) replicator is not really an oversight, just probably not well enough advertised in the stub 0E0P LifeWiki article, or anywhere else yet. The

original introductory article by calcyman was titled "Fully self-directed replication", and it describes the 0E0P as follows:

Suitably programmed, this is a parity-rule replicator, and a loop-like replicator, and a universal constructor. It is also the first unbounded-fecundity replicator in Conway’s 2-state cellular automaton.
