摘要
日本学者Seiichi Abe在2002年证明了有限单群A1(q),Sz(q),3D4(q),G2(q),2G2(q)可仅用可解子群的阶的集合进行刻画.本文证明了对所有散在单群可仅用可解子群的阶集合进行刻画.
In this paper the author have proved the following theorem, which solves a problem of S. Abe and N. Iiyori for sporadic simple groups.Theorem:Let G≌ be a finite group and S be one of sporadic simple groups,then G≌S if and only if Ord ( Ssol (G) ) = Ord ( Ssol ( S ) ), where Ord ( Ssol ( G ) ) is the set of orders of solvable subgroups in G.
