Let ψ be a homomorphism from a group Ⅱ to a group Aut(N). Denote by Hψ×N the semidirect product of N by H with homomorphism ψ. This paper proves that: Let G be a finite nonsolvable group. If G has exactly 40 maximal order elements, then G is isomorphic to one of the following groups: (1) Z4ψ×A5,kerψ = Z2; (2) D8ψ× A5, kerψ = Z2×Z2; (3) G/N = S5, N = Z(G) = Z2; (4) G/N = S5, N = Z2 × Z2, N ∩ Z(G) = Z2.
