摘要

We define a new non-identity characteristic subgroup, D* (S), of a finite p-group S. and prove that D* (S) is characteristic in a significant family of p-stable finite groups G having S as a Sylow p-subgroup. This result is analogous to an earlier result about Z J (S) by the first author and has a very short proof.
