# Abnormal normalizer not implies pronormal

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., subgroup with abnormal normalizer) neednotsatisfy the second subgroup property (i.e., pronormal subgroup)

## Statement

A subgroup whose normalizer is an abnormal subgroup need not be pronormal.

## Facts used

## Proof

The proof follows directly by combining facts (1) and (2).
