三次对称群的一个特征性质

A Characteristic Property of the Semmetric Group on 3 Letters

本文给出三次对称群 S_3的一个特征性质:有限群 G 恰有两个非线性共轭类当且仅当GS_3。

In this paper,a characteristic property of the semmetric group S_3 on 3 letters is given:A finite group G has exactly two non-linear conjugacy classes if and only if G(?)S_3.
