Abstract:
It is proved that for any finite group $G$ possessing a $p$-complement $H$ for some prime number $p$, the following assertions are equivalent: (1) all $p$-complements of $G$ are selfnormalizable; (2) all $p$-complements of $G$ are abnormal; (3) the subgroup $H$ is abnormal in $G$; (4) $NG(HX)=HX$ for any $X\trianglelefteq G$; (5) $G$ does not contain central chief pfactors.
Keywords:
$p$-complement, abnormal subgroup, pronormal subgroup, Hall subgroup.
