Previous work demonstrates that strict heterochiral replication of self-replicating loops in two-dimensional cellular automaton space is not possible under any single cell-state transition function, but a less-strict functional heterochirality is possible with the introduction of a different broken symmetry: a cell state-set permutation applied exclusively to left- (or right-) handed replication. A new result reported here is that up to two different state-set permutations applied to one replication chirality can support functionally-heterochiral replication of the J. Byl self-replicating structure in one common cellular automata space.
