Definition

A group in which every permutable subgroup is normal is a group such that every permutable subgroup of the group is a normal subgroup of the group.

Formalisms

In terms of the subgroup property collapse operator

This group property can be defined in terms of the collapse of two subgroup properties. In other words, a group satisfies this group property if and only if every subgroup of it satisfying the first property (permutable subgroup) satisfies the second property (normal subgroup), and vice versa.
