This article defines a subgroup property: a property that can be evaluated to true/false given a group and a subgroup thereof, invariant under subgroup equivalence. View a complete list of subgroup properties[SHOW MORE]
Relation with other properties
- Intermediately fully characteristic subgroup
- Fully characteristic subgroup
- Strictly characteristic subgroup
- Intermediately 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.
- The omega subgroups of a group of prime power order are homomorph-containing. Further information: Omega subgroups are homomorph-containing
This subgroup property is trim -- it is both trivially true (true for the trivial subgroup) and identity-true (true for a group as a subgroup of itself).

Intermediate subgroup condition
YES: This subgroup property satisfies the intermediate subgroup condition: if a subgroup has the property in the whole group, it has the property in every intermediate subgroup.

YES: This subgroup property is join-closed: an arbitrary (nonempty) join of subgroups with this property, also has this property.
