Popis: Let G be a finite group having a π-subgroup H such that |G: H| is not divisible by the numbers in π. In this case, the subgroup H is referred to as a π-Hall subgroup, and the group G by itself is referred to as a Eπ-group. If, moreover, the group H is supersolvable, then G is referred to as an Eπu-group. It is proved in the paper that the class of all Eπu-groups is a solvably saturated formation, and the proof is carried out without using the classification of finite groups.
