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.
