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]
In terms of the transfer condition operator
This property is obtained by applying the transfer condition operator to the property: fully invariant subgroup

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

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).

YES: This subgroup property is intersection-closed: an arbitrary (nonempty) intersection of subgroups with this property, also has this property.
In fact, since the property is also true for every group as a subgroup of itself, it is a strongly intersection-closed subgroup property.
