Why isn't this graph: 1-2 3 asymetric? I think there exists only one automorphism: 2-1 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 non-trivial symmetries and permutation (1 2) is already a non-trivial symmetry. Sorry to bother
