Abstract
In this article, we prove a conjecture of J. G. Thompson for the finite simple group 2 D n (q). More precisely, we show that every finite group G with the property Z(G) = 1 and N(G) = N(2 D n (q)) is necessarily isomorphic to 2 D n (q). Note that N(G) is the set of lengths of conjugacy classes of G.
