Let G  be a finite p -group. We show that if Ω2(G ) is an extraspecial group then Ω2(G ) = G  . If we assume only that

(the subgroup generated by elements of order p 2 ) is an extraspecial group, then the situation is more complicated. If p = 2, then either
 = G  or G   is a semidihedral group of order 16. If p > 2, then we can only show that
 = Hp (G  ).
