Definition
Symbol-free definition
A group is said to satisfy the normalizer condition, if it satisfies the following equivalent conditions:
- The normalizer of any proper subgroup properly contains it
- There is no proper self-normalizing subgroup
- Every subgroup is ascendant
Definition with symbols
A group is said to satisfy a normalizer condition if for any proper subgroup of , with the inclusion being strict (that is, is properly contained in its normalizer).
Groups satisfying the normalizer condition have been termed N-groups but the term N-group is also used for groups with a particular condition on normalizers of solvable subgroups.

- Nilpotent group: It turns out that for a finitely generated group, the two properties are equivalent. For full proof, refer: Nilpotent implies normalizer condition
