## 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 of
- Every subgroup of is ascendant

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.

## Metaproperties

Metaproperty name | Satisfied? | Proof | Statement with symbols |
---|---|---|---|

subgroup-closed group property | Yes | If is a group satisfying normalizer condition, and is a subgroup of , then also satisfies normalizer condition. | |

quotient-closed group property | Yes | If is a group satisfying normalizer condition, and is a normal subgroup of , then the quotient group also satisfies normalizer condition. |
