## Statement

Suppose $H \le K \le G$ are groups such that $H$ is a strictly characteristic subgroup of $G$ and $K/H$ is a strictly characteristic subgroup of the quotient group $G/H$. Then, $K$ is a strictly characteristic subgroup of $G$.

### Generalizations

Quotient-balanced implies quotient-transitive. Other special cases of this are:

## Proof

Given: Groups $H \le K \le G$ such that $H$ is strictly characteristic in $G$ and $K/H$ is strictly characteristic in $G/H$.

To prove: $K$ is strictly characteristic in $G$.
