The positive-soliton multi-soliton conjecture for a6(n,k)

Positive solitons are configurations of the cellular automaton $\Phi(n,k)$ in their minimal forms, and a multi-soliton solution is a configuration consisting of several such positive solitons. Positive-soliton multi-soliton conjecture. Combining positive solitons gives rise to multi-soliton solutions as in condition (iii) at the beginning of this subsection. This predicts that the positive-soliton scattering examples extend to arbitrary combinations of positive solitons.
