Let g:{0,1}Z2→{0,1}Z2 be Conway's Game of Life map. Does g strongly simulate every block map ϕ:Y→DZ2 whose domain Y is a two-dimensional subshift of finite type? Explicitly, for every such ϕ, do there exist positive integers m,n, an injective macrotile substitution τ:D→{0,1}[m]×[n], and a bijective partial block map h from the Life configurations x satisfying g(x)∈τ(DZ2) onto Y, such that g(x)=τ(ϕ(h(x))) for every such x?
