- Fully characteristic subgroup
- Strictly characteristic subgroup
- Characteristic subgroup
- Isomorph-free subgroup in case the subgroup is co-Hopfian as a group: it is not isomorphic to any proper subgroup of itself.

## Facts

- The omega subgroups of a group of prime power order are homomorph-containing.
