The n-dimensional SierpiΕski gasket X, spanned by n + 1 vertices, has (n + 1)! symmetries acting as the symmetric group on the vertices. The object of this note is the remarkable observation that for n 2 every topological automorphism of X is one of these symmetries. A modification of the arguments
