## Definition

A **group in which every normal subgroup is a direct factor** is a group with the property that every normal subgroup of the group is a direct factor 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 (normal subgroup) satisfies the second property (direct factor), and vice versa.
