Abstract

The topological symmetry group TSG(Γ)\mathrm{TSG}(\Gamma) of an embedding Γ\Gamma of a graph in S3S^3 is the subgroup of the automorphism group of the graph which is induced by homeomorphisms of (S3,Γ)(S^3,\Gamma). If we restrict to orientation preserving homeomorphisms then we obtain the orientation preserving topological symmetry group TSG+(Γ)\mathrm{TSG}_+(\Gamma). In this paper we determine all groups that can be TSG(Γ)\mathrm{TSG}(\Gamma) or TSG+(Γ)\mathrm{TSG}_+(\Gamma) for some embedding Γ\Gamma of a generalized Petersen graph other than the exceptional graphs P(12,5)P(12,5) and P(24,5)P(24, 5) (which will be addressed in a separate paper.
