A permutation graph over a graph was introduced by Lee and Sohn in [8] as a generalization of both a graph bundle over a graph and a standard permutation graph, and they gave a characterization of a natural isomorphism and an automorphism of a given permutation graph over a graph. In this paper, we enumerate the natural isomorphism classes of cycle… (More)
