Let be a partition of the set of all primes , and let G be a finite group. A set of subgroups of G is said to be a complete Hall-set of G if every member of is a Hall σi-subgroup of G for somei ∈ I and contains exactly one Hall σi-subgroup of G for every i such that . In this paper, we study the structure of G under the assuming that some subgroups of G permutes with all members of .
