The automorphic A-chromatic index of a graph Γ is the minimum integer m for which Γ has a proper edge-coloring with m colors which is preserved by a given subgroup A of the full automorphism group of Γ.We compute the automorphic A-chromatic index of each generalized Petersen graph when A is the full automorphism group.
