A subgroup H of G is called QΦ-supplemented in G if there exists a subgroup T of G such that G = HT and (H∩T)HG/HG ≤ Φ(H/HG), where HG is the maximal normal subgroup of G contained in H and Φ(H/HG) is the Frattini subgroup of H/HG. In this paper, we study the properties of the QΦ-supplemented subgroups and use them to determine the structure of finite groups.
