Ticket #27695 – Description
initial v1 25 25 26 26 Solution 2: enforce the fact that graph6 and dig6 representations make sense 27 only for graphs with vertex set `range(n)` and raise an error otherwise. (The current code silently encodes an isomorphic graph.) 27 only for graphs with vertex set `range(n)` and raise an error otherwise. (The current code silently encodes an isomorphic graph.) Then use this directly to access vertices. 28 28 29 29 To put things in perspective, these representations are barely used outside of `cluster_algebra_quiver` so neither solution would have a big impact on other code. On the contrary in `cluster_algebra_quiver` they are used extensively as a way of comparing isomorphism classes of quivers. This is not the right way of doing so (one should use `sage.graphs.generic_graph.GenericGraph.canonical_label` instead) but, personally, I do not thing that reimplementing `cluster_algebra_quiver` is worth the effort.
