摘要: 设G是有限群. 如果G至少有一个共轭类C的长|C|被两个不同的素数整除, 则定义ccl2(G)=max{|C||C|是G的共轭类, 且|C|被至少两个不同的素数整除}; 如果G的各共轭类的长是素数的幂, 则规定ccl2(G)=0. 讨论当ccl2(G)≠0时, ccl2(G)给定的上界对有限非可解群G结构的影响.

Abstract: Let G be a finite group. If G has at least one conjugacy class C  such that  |C| is divisible by at least two distinct primes, then we define ccl2(G)=max{|C||C| is a conjugacy class of G such that |C| is divisible by at least two distinct primes}. The purpose of this paper is to  discuss the influence of a given upper bound of ccl2(G) on the structure of a  nonsolvable group G when ccl2(G)≠0.

Key words: conjugacyclasslength, finite non-solvable group, structure, prime number
