Abstract

We study cube-complementary graphs, that is, graphs whose com- plement and cube are isomorphic. We prove several necessary conditions for a graph to be cube-complementary, describe ways of building new cube-complementary graphs from existing ones, and construct
infinite families of cube-complementary graphs.

Keywords: Graph cube, cubeco graph, Graph complement, Graph iso- morphism, Circulant graph, Radius and Diameter of a graph.
