The question allows anisotropic rules, but anisotropic rules can't achieve S^(MN) except with 1 state or in a 1 by 1 grid. The dvgrn-argument shows for any rule, isotropic or not, you can only get max(S,S^(MN)-S) ... Which is not much of a reduction in the upper bound, but at least it's something! ...
