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]
A subgroup of a group is termed a join of finite normal subgroups if it can be expressed as a join of subgroups, all of which are finite normal subgroups of the whole group.
