摘要：
Let G be a finite group and let cd(G) be the set of irreducible character degrees of G. The degree graph Delta(G) is the graph whose set of vertices is the set of primes that divide degrees in cd(G), with an edge between p and q if pq divides a for some degree a is an element of cd(G). It is shown using the degree graphs of the finite simple groups that if G is a nonsolvable group, then the diameter of Delta(G) is at most 3. (c) 2007 Elsevier Inc. All rights reserved.
