摘要

通过有限群G的共轭类长集合cs(G)来刻画有限群A6S6,得到如下结论:如果csG)=csG)={1, p3·r,p·q2·r,p3·q2,q2·r},则G=A6;如果csG)={1,q·r,p3·r,q2·r,p·q2·r,p3·q·r,p4·q2},则G=S6.

Abstract

This paper characterizes the groups A6 and S6  by the set of size of conjugacy classes, and gets the following results: If cscsG)=csG)={1, p3·r,p·q2·r,p3·q2,q2·r}, then G=A6; If csG)={1,q·r,p3·r,q2·r,p·q2·r,p3·q·r,p4·q2}, then G=S6.
