## Statement

### Property-theoretic statement

The subgroup property of being characteristic satisfies the subgroup metaproperty of being transitive.

### Verbal statement

A characteristic subgroup of a characteristic subgroup is characteristic in the whole group.

### Symbolic statement

Let $H$ be a characteristic subgroup of $K$, and $K$ a characteristic subgroup of $G$. Then, $H$ is a characteristic subgroup of $G$.
