Let d(G) denote the minimal number of generators of the finite p-group G, r(G) the maximum over all subgroups H of G of d(H) and ra(G) the maximum over all abelian subgroups H of G of d(H). If G is of class two it is clear that

By considering properties of the stability number of graphs we construct examples which show that any value of r(G) within these bounds can occur.
