Nilpotent and every abelian characteristic subgroup is central implies class at most two

Contents

Statement

If G is a Nilpotent group (?) and satisfies the property that every Abelian characteristic subgroup of it is central, then the nilpotence class of G is at most two.

Proof

The proof follows direct from fact (1): it shows that in a nilpotent group of class at least three, we have an Abelian characteristic subgroup that is not central (namely, the penultimate term of the lower central series).
