Ż?, which is formed from theunion of?and its complement Ż?by adding an edge between each pair of identical ver-tices in?and Ż?. Vertex-transitive self-complementary graphs provide vertex-transitivecomplementary prisms. It was recently proved by the author that? Ż?is a core, i.e. all itsendomorphisms are automorphisms, whenever?is vertex-transitive, self-complementary,and either?is a core or its core is a complete graph. In this paper the same conclusion isobtained for some other classes of vertex-transitive self-complementary graphs that can bedecomposed as a lexicographic product? = ?1?2.
