Abstract

Let HH be a subgroup of a group GG. The permutizer PG(H)P_G(H) is the subgroup generated by all cyclic subgroups of GG which permute with HH. A subgroup HH of a group GG is strongly permutable in GG if PU(H)=UP_U(H)=U for every subgroup UU of GG such that~HUGH\le U\le G. We investigate groups with P\mathbb{P}-subnormal or strongly permutable Sylow and primary cyclic subgroups. In particular, we prove that groups with all strongly permutable primary cyclic subgroups are supersoluble.
