WebDetermine the average degree, number of edges, diameter, girth, and circumference of the hypercube graph Qd. Proof. Since V is the set of all 0 - 1 sequences of length d. Thus total number of vertices is 2d, since in each place we can assign two number 0,1. Since two such sequence form an edge if and only if they differ in exactly one position.
