Finite groups with three conjugacy class sizes of certain elementsQuinhui Jiang, Changguo ShaoSchool of Mathematics, University of Jinan, Shandong, ChinaAbstract: Let $G$ be a finite group and $m,n$ two positive coprime integers. We prove that the set of conjugacy class sizes of primary and biprimary elements of $G$ is $\{1,m,n\}$ if and only if $G$ is quasi-Frobenius with abelian kernel and complement. Keywords: finite groups; conjugacy class sizes; primary and biprimary elements Classification (MSC2000): 20D10; 20E45 Full text of the article: (for faster download, first choose a mirror)
