Why isn't this graph:
12 3 asymetric? I think there exists only one automorphism: 21 3 but I'm also supposed to prove that ther are no asymetric graphs with 1<V(G)<=5 so it can't be assymetric

Oh I see now! It can have no nontrivial symmetries and permutation (1 2) is already a nontrivial symmetry.
Sorry to bother
