Abstract: As a generalization of $ (t)$-groups and of $ (q)$-groups, a group $ G$ is called a $ (\pi - q)$-group if every subnormal subgroup of $ G$ permutes with all Sylow subgroups of $ G$. It is shown that if $ G$ is a finite solvable $ (\pi - q)$-group, then its hypercommutator subgroup $ D(G)$ is a Hall subgroup of odd order and every subgroup of $ D(G)$ is normal in $ G$; conversely, if a group $ G$ has a normal Hall subgroup $ N$ such that $ G/N$ is a $ (\pi - q)$-group and every subnormal subgroup of $ N$ is normal in $ G$, then $ G$ is a $ (\pi - q)$-group.
