Abstract
LetK be a characteristic subgroup of ap-groupH such thatH induces onK a sufficiently large group of automorphisms. ThenH cannot be embedded as a normal subgroup contained in the Frattini subgroup in any finite group. The groupH may have a large center without any characteristic subgroup ofH properly contained in it. Examples are given for suchH withZ(H) elementary abelian of arbitrary dimension.
