We show that if p is an odd prime and G is a finite group satisfying the condition that p2 divides the degree of no irreducible character of G , then |G:Op(G)|p⩽p4, where Op(G) is the largest normal p ‐subgroup of G , and if P is a Sylow p ‐subgroup of G , then P'' is subnormal in G . Our investigations suggest that if pa is the largest power of p dividing the degrees of irreducible characters of G , then |G:Op(G)|p is bounded by pf(a), where f(a) is a function in a and P(a+1) is subnormal in G .
