Let H be a graph on n vertices and G a collection of n subgraphs of H , one for each vertex. Then G is an orthogonal double cover (ODC) of H if every edge of H occurs in exactly two members of G and any two members share an edge whenever the corresponding vertices are adjacent in H . ODCs of complet
An orthogonal double cover (ODC) of Kn is a collection of graphs such that each edge of Kn occurs in exactly two of the graphs and two graphs have precisely one edge in common. ODCs of Kn and their generalizations have been extensively studied by several authors (e.g. in:
Several isomorphism classes of graph coverings of a graph G have been enumerated by many authors. Kwak and Lee (Canad. J. Math. XLII (1990) 747) enumerated the isomorphism classes of graph bundles and those of n-fold coverings with respect to a group of automorphisms of the base graph G which ΓΏx a s
