## Definition

### Symbol-free definition

A subgroup of a group is termed intermediately normal-to-characteristic if it satisfies the following equivalent conditions:

### Definition with symbols

A subgroup $H$ of a group $G$ is termed intermediately normal-to-characteristic in $G$ if it satisfies the following equivalent conditions:

• For any subgroup $K$ of $G$ containing $H$ such that $H$ is normal in $K$, $H$ is characteristic in $K$.
• $H$ is characteristic in any subgroup of $G$ contained in its normalizer $N_G(H)$.

## Formalisms

### In terms of the in-normalizer operator

This property is obtained by applying the in-normalizer operator to the property: intermediately characteristic subgroup

A subgroup $H \le G$ is intermediately normal-to-characteristic in $G$ if and only if $H$ is an intermediately characteristic subgroup in $N_G(H)$.

## Metaproperties

### Intermediate subgroup condition

YES: This subgroup property satisfies the intermediate subgroup condition: if a subgroup has the property in the whole group, it has the property in every intermediate subgroup.
