摘要
本文对若干包含在有限超可解群类的正规子群闭的群系,给出一类利用一个特殊的正规子群和一个特殊的极大子群共同来刻划的方法。
This paper provides a new method of charaterizing some formations which are contained in the class of finite supersolvable groups and are closed for normal subgroups, with the help of a special normal subgroup and a special maximal subgroup,in which, the special normal subgroup satisfies the condition that the normal subgroup and its quotient group belong to the formation.
