Category:Characteristic Subgroups

This category contains results about Characteristic Subgroups.

Let $G$ be a group.

Let $H$ be a subgroup such that:

$\forall \phi \in \Aut G: \phi \sqbrk H = H$

where $\Aut G$ is the automorphism group of $G$.

Then $H$ is characteristic (in $G$), or a characteristic subgroup of $G$.
