Inner automorphism

An **inner automorphism** is a specific type of automorphism of a group that arises from the structure of the group itself. In group theory, an automorphism is a bijective homomorphism from a group to itself, meaning it is a structure-preserving map that reflects the group's operations. An inner automorphism can be defined as follows: Let \( G \) be a group and let \( g \) be an element of \( G \).
