摘要：

Let G be a finite group and cd(G) denote the set of complex irreducible character degrees of G. We prove that if G is a finite group and H is an almost simple group whose socle is a sporadic simple group H-0 and such that cd(G) = cd(H), then G' congruent to H-0 and there exists an abelian subgroup A of G such that G/A is isomorphic to H. In view of Huppert's conjecture, we also provide some examples to show that G is not necessarily a direct product of A and H, so that we cannot extend the conjecture to almost simple groups.
