### On some arithmetic properties of nite groups

#### Abstract

Let be some partition of the set of all primes . A group is called \emph{-primary} if is a finite -group for some . We say that a finite group is: \emph{-soluble} if every chief factor of is -primary; \emph{-nilpotent} if is the direct product of some -primary groupsBeing based on these concepts, we develop and unify some aspects of the theories of soluble, nilpotent, supersoluble and quasinilpotent groups, the subgroup lattices theory, the theories of generalized quasinormal and generalized subnormal subgroups
