Abstract

Let G be a finite group and cd(G) denote the set of complex irreducible character degrees of G. We prove that if H2.M12 is a sporadic quasisimple group that cd(G)=cd(H), then there exists an Abelian subgroup A of G such that G is isomorphic to a central product of H and A.

摘要

G ^是有限群和CDG ^)表示一套复杂不可约特征度的G ^。我们证明H2个中号12 是一个零散的quasisimple组, CdG=CdH然后存在G的一个Abelian子群A,使得GHA的中心乘积同构。
