## Definition

### Symbol-free definition

A subgroup of a group is termed a **subgroup of Abelian normal subgroup** if it satisfies the following equivalent conditions:

- It is a subgroup of an Abelian normal subgroup.
- It is a normal subgroup of an Abelian normal subgroup.
- It is a central subgroup (i.e., it is contained in the center) of a normal subgroup.
