{wiki=Class_automorphism}
In mathematics, particularly in the field of group theory and algebra, a class automorphism refers to a specific type of automorphism of a group, particularly in the context of a class of structures, such as groups or rings. \#\#\# Definition of Automorphism An **automorphism** is an isomorphism from a mathematical structure to itself. In simpler terms, it's a bijective (one-to-one and onto) mapping of a structure that preserves the operations defined on that structure.
