The conditions of the existence and the conjugacy of $\frak{X}$-covering subgroups in finite $\pi$-soluble group for Schunck class $\frak{X}$ were obtained. In a number of papers (with A. F. Vasil'ev) the new properties of formation of all finite groups having chief series with simple factors were proved; Schunck classes $\frak{X}$ and local formations $\frak{F}$ of finite soluble groups with the condition that $\frak{X}$ contains each group $G=AB=BC=CA$, where $A\in\frak{X}\cap\frak{F}$, $B\in\frak{X}\cap\frak{F}$ and $C\in\frak{X}$, were investigated; a new characterization of finite metanilpotent groups was obtained: a finite group $G$ is metanilpotent if and only if every subformations of $form G$ is abnormally hereditary.
