For n a positive integer, a group G is called core-n if H/H_G has order at most n for every subgroup H of G (where H_G is the normal core of H, the largest normal subgroup of G contained in H). It is proved that a finite core-p p-group G has a normal abelian subgroup whose index in G is at mostp 2 if p>2, which is the best possible bound, and at most 2^6 if p=2.

Abstract

For n a positive integer, a group G is called core-n if H/H_G has order at most n for every subgroup H of G (where H_G is the normal core of H, the largest normal subgroup of G contained in H). It is proved that a finite core-p p-group G has a normal abelian subgroup whose index in G is at mostp 2 if p>2, which is the best possible bound, and at most 2^6 if p=2.
