# Normal not implies strongly potentially characteristic

This article gives the statement and possibly, proof, of a non-implication relation between two subgroup properties. That is, it states that every subgroup satisfying the first subgroup property (i.e., normal subgroup) neednotsatisfy the second subgroup property (i.e., characteristic-potentially characteristic subgroup)

## Contents

## Statement

### Verbal statement

A normal subgroup need not be characteristic-potentially characteristic.

### Statement with symbols

It is possible to have a group and a normal subgroup of such that there is no group containing in which both and are characteristic subgroups.

## Facts used

## Proof

The proof follows directly from facts (1) and (2).
