 Apr 8 comment Mapping graphs to themselves, e.g. the meta-graph @Graffitics sorry for the basic question, but would the given examples shown count as graph homomorphisms?

I know that this is vague (hence the question), but imagine a normal two sphere: you can parameterize it by spherical coordinates $\phi, \psi$. Two arcs would be 100% similar if the change along the parametrized paths would invoke approximately the same change in these coordinates. Jun 25 comment Comparing geodesics on a hypersphere @AmitaiYuval there is absolutely no guarantee that they intersect, in fact most of them don't. Jun 25 asked Comparing geodesics on a hypersphere Jun 3 accepted Spare storage of a tree Jun 2 comment Spare storage of a tree Perfect! I was looking for a labeling like this! I knew there was some $N$ at which you couldn't store a tree using a single 64-bit integer -- obviously there are an infinite such trees. Jun 2 comment Spare storage of a tree @Gamamal even for connected graphs, isn't every tree a spanning tree to some graph? For example, shouldn't every tree be a spanning tree to the complete graph? Jun 2 comment Spare storage of a tree @Gamamal there was no restriction that the graph had to be connected, thus a spanning tree might not exist.
