In this paper, closed groups and proper subgroup are classified.
本文对闭群和真子群进行了分类。
The finite inner-(2,2')-closed groups were classified and this class of finite groups with every non-maximal proper subgroup of even order of(2,2')-closed were also classified.
本文首先分类了内-（2，2＇）-闭群，再对每个非极大偶阶真子群为（2，2＇）-闭的不可解群进行了分类。
