摘要
本文获得了以下结果:设G为有限超特殊p-群.则下列条件等价:(1)G的非平凡特征子群的阶相同;(2)G的非平凡特征子群唯一;(3)当p>2时,expG=p;当p=2时,G(?)D_8.
In this paper, we studied finite p-groups all of whose nontrivial characteristic subgroups have the same order. We get that if G is a finite superspecial p-group, then the following conditions are equivalent: (1) Nontrivial characteristic subgroups of G have the same order; (2) G has unique nontrivial characteristic subgroup; (3) If p 〉 2, exp G =p, if p = 2, G ≠ Ds.
