AnSTRACr. Let G be a graph, and let v be a vertex of G. We denote by N(v) the set of vertices of G which are adjacent to v, and by (N(v)) the subgraph of G induced by N(v). We call <N(v)) the neighborhood of v. In a paper of 1968, Agakishieva has, as one of her main theorems, the statement: "Graphs
