SUMMARY

The discussion centers on the properties of asymmetric graphs, specifically addressing a graph with three nodes represented as 1-2 and 3. It concludes that this graph cannot be asymmetric due to the existence of a non-trivial symmetry, namely the permutation (1 2). The user also references the requirement to prove that no asymmetric graphs exist for the vertex count range of 1 < |V(G)| <= 5, reinforcing the conclusion that the graph in question is not asymmetric.

PREREQUISITES
  • Understanding of graph theory concepts, particularly automorphisms
  • Familiarity with symmetric and asymmetric graph definitions
  • Knowledge of permutations and their implications in graph structures
  • Basic comprehension of vertex sets and their properties in graph theory
NEXT STEPS
  • Research the properties of automorphisms in graph theory
  • Study the classification of symmetric vs. asymmetric graphs
  • Explore examples of graphs with varying vertex counts to identify symmetry
  • Learn about the implications of non-trivial symmetries in graph structures
USEFUL FOR

Mathematicians, computer scientists, and students studying graph theory, particularly those interested in the properties of asymmetric graphs and automorphisms.

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 asymmetric

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