All groups considered are finite. Let $$\mathcal {F}$$ be a formation. A subgroup H of a group G is called K- $$\mathcal {F}$$ -subnormal in G if there exists a chain of subgroups $$\begin{aligned} H=H_{0} \subseteq H_{1} \subseteq \cdots \subseteq H

Let $$\sigma = \{ {\sigma }_{i} : i \in I \}$$ be a partition of the set $${\mathbb {P}}$$ of all prime numbers. A subgroup X of a finite group G is called $$\sigma $$ -subnormal in G if there is a chain of subgroups $$\begin{aligned} X=X_{0} \subset

Let G be a finite group and let r be a prime divisor of the order of G. We prove that if r ≥ 5 and G has the E { r , t } -property for all t ∈ π ( G ) \ { r } , then G is r-solvable. A group G is said to have the E π -property if G possesses a

Subgroup-closed saturated formations F which are closed under taking products of F -subnormal F -subgroups are studied in the paper. Our results can be regarded as further developments in the hunt for a solution of a problem proposed by L.A. Shemetko
