A group in which every normal-extensible automorphism is inner is a group wit hthe property that every normal-extensible automorphism of a group is an inner automorphism.


In terms of the automorphism property collapse operator

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