Abstract: Let X and Y be compact metric spaces. Let $ S(X,Y)$ denote the collection of standard maps of X onto Y. We establish that $ S(C,Y)$ is a dense subset of $ C(C,Y)$, where C is the Cantor set. If f is a standard map and $ G(f,Y)\{ A(f,Y)\} $ denotes the subgroup of $ H(X)$ which preserves {interchanges} the point-inverses of f, then there is a continuous homomorphism of $ A(f,Y)$ into $ H(Y)$ with kernel $ G(f,Y)$. We also show that $ G(f,Y)$ and $ A(f,Y)$ are closed subsets of $ H(X)$.
