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]

Definition

A subgroup H of a group G is termed strongly permutably complemented in G if there exists a permutable complement K to H in G, such that, for any subgroup LH, K and L are permuting subgroups.

Metaproperties

Transitivity

This subgroup property is transitive: a subgroup with this property in a subgroup with this property, also has this property in the whole group.

If HKG are such that H is strongly permutably complemented in K and K is strongly permutably complemented in G, then H is strongly permutably complemented in G. For full proof, refer: Strongly permutably complemented is transitive

Trimness

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.
