The Kneser graph KG(n,k) is the graph whose vertex set consists of all k-subsets of an n-set, and two vertices are adjacent if and only if they are disjoint. The Schrijver graph SG(n,k) is the subgraph of KG(n,k) induced by all vertices that are 2-stable subsets. The square G2 of a graph G is defined on the vertex set of G such that distinct vertices within distance two in G are joined by an edge...
