Let X, 0 be a nonαlog-canonical, quasi-homogeneous surface singularity germ. Ε½ . And let G ; Aut X, 0 be the maximal reductive subgroup. In this paper we bound the order of GrC U by yP ΠΈ P, a purely topological invariant. Hurwitz's theorem comes out as a corollary. We use the standard approach of ta
