摘要：

For an irreducible character chi of a finite group G, the codegree of chi is defined as divide G: ker(chi) divide /chi(1). In this paper, the authors determine finite nonsolvable groups with exactly three nonlinear irreducible character codegrees, which are L2(2f) for f >= 2, PGL2(q) for odd q >= 5 or M10.
