WebK(n,k)), and the Johnson graph, respectively. Note that the adjacency matrix of J(n,k,k) is the identity matrix; that is A 0 = I. In the following lemma, we observe that most of the generalized Johnson graphs are connected. Lemma 2.7. The graph J(n,k,i) is connected if the non-negative integer i satisfies 2k −n < i < k. Proof. Consider a ... WebDec 1, 2024 · Lemma 1.3.1 If x is a vertex of the graph X and g is an automorphism of X, then the vertex y = x g has the same valency as x. Proof: Let N ( x) denote the subgraph of X induced by the neighbors of x in X. Then. N ( x) g = N ( x g) = N ( y), and therefore N ( x) and N ( y) are isomorphic subgraphs of X. Consequently, they have the same number of ...
