1.Why [itex] Aut(G)=S_G[/itex] implies G is trivial?
I search through the internet and no answer.2.Here is another very difficult conception question which has different answers from my professor and wikipedia:
Difference between Symmetry group,automorphism group and Permutation group?
From wikipedia:automorphism group is, "loosely" speaking, the symmetry group of the object.
My guess is Symmetry group equals Permutation group? and automorphism group is smaller?
