Complete group
In mathematics, a group G is said to be complete if all the automorphisms of G are inner.
As an example, all the symmetric groups Sn are complete except when n = 6. For a simple group G, the automorphism group G is complete, i.e. Inn(Aut(G)) = Aut(Aut(G)).
More examples would be useful...
