Abstract:
We construct infinite series of subgroup $m$-functors and regular subgroup $m$-functors $\theta$ such that the Frattini $\theta$-subgroup of every normal Hall subgroup $H$ in any finite group $G$ is equal to the intersection of $H$ with the Frattini $\theta$-subgroup of $G$.
Keywords:finite group, Hall subgroup, subgroup $m$-functor, Frattini $\theta$-subgroup.
