Sporadic composition factors of finite groups isospectral to simple groups
A. M. Staroletov Sobolev Institute of Mathematics, pr. Koptyuga, 630090, Novosibirsk, Russia
Abstract:
This paper considers a group which has a nonabelian sporadic composition factor and the same set of element orders as a finite simple group. It is proved that such group is isomorphic to $U_5(2)$ or a sporadic group.
Keywords:
recognition by spectrum, sporadic groups, finite simple groups.
