A simple graph is called semi-symmetric if it is regular and edge transitive but not vertex transitive. In this paper we prove that there is no connected cubic semi-symmetric graph of order $12p^3$ for any prime number $p$.
Keywords: Edge-transitive graph, vertex-transitive graph, semi-symmetric graph, order of a graph, classification of cubic semi-symmetric graphs
