## automorphismAn automorphism is an isomorphism from a set onto itself. An automorphism group of a group G is the group formed
by the automorphisms of G (bijections from G to itself
which preserve the multiplication). Similarly, one can consider the automorphism
groups of other structures such as rings and graphs, by looking at bijections which preserve
their mathematical structure. ## Related category• GROUPS AND GROUP THEORY | |||||
