Graph Distance Graph


For a connected graph G of graph diameter d, the graph distance-k graph G_k for k=1, ..., d is a graph with the same vertex set and having edge set consisting of the pairs of vertices that lie a graph distance k apart. It is therefore the case that G_1=G (Brouwer et al. 1989, p. 437).

Graph distance graphs differ from Euclidean distance graphs in that the former are constructed based on graph distance between vertices, while the latter are constructed based on Euclidean distance.

Special classes of graphs isomorphic to their own graph k-distance graph are summarized in the table below.

k>1(3k-1)-antiprism graph
k>1 odd(k,3)-caveman graph
k>1 oddprism graph P_2 square C_(2k)
k>1 odd2(k-1)-sunlet graph
k>1torus grid graph C_(n+1) square C_(n+1)
k>2 oddhypercube graph Q_(n+1)

Notable graphs that are isomorphic to their own distance-k graph are summarized in the following table.
