WebAn arc-transitive graph, sometimes also called a flag-transitive graph, is a graph whose graph automorphism group acts transitively on its graph arcs (Godsil and Royle 2001, p. 59). More generally, a graph G is called s-arc-transitive (or simply "s-transitive") with s>=1 if it has an s-route and if there is always a graph automorphism of G sending each s-route … WebThis paper constructs two sequences of graphs.

WebMay 22, 2015 · 3. I have problems to prove wheter a regular graph is vertex-transitive or not. For instance, consider the following examples: the generalized Petersen graphs P 2, 7, P 3, 8 and the Folkman graph. For the three of them it is known wheter or not they are vertex-transitive, but it's never explained the reason. Of course you can always try to … WebHowever, modeling directed graphs that both contain cycles and some element of transitivity, two properties common in real-world settings, is challenging. Box embeddings, which can be thought of as representing the graph as an intersection over some learned super-graphs, have a natural inductive bias toward modeling transitivity, but (as we ...
