WebThe generalized Johnson graph GJ(n,k,l) is the graph whose vertex set consists of all k-subsets of [n], two of which are adjacent if they have exactly l elements in common. Thus GJ(n,k,k−1) = J(n,k) and GJ(n,k,0) = K(n,k). Johnson graphs have been widely studied in the literature. This is in part for their applications in

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 ...
