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 of a group is termed an intersection of automorph-conjugate subgroups if it can be expressed as the intersection of (possibly infinitely many) automorph-conjugate subgroups.

Formalisms

In terms of the intersection-closure operator

This property is obtained by applying the intersection-closure operator to the property: automorph-conjugate subgroup
