Automorphism group of edge symmetry

asked 5 years ago

I asked a similar question before,

https://ask.sagemath.org/question/427...

I am curious that is there any similar function for finding "edge symmetry"?

Note: the link I provided is for "node symmetry" in a network (graph).

Can you clarify what you mean by an example? Do you mean the set of permutations of (labeled) edges induced by permutations of vertices?

What about g.line_graph().automorphism_group()?

In most cases this group coincides with the edge automorphism group (see for instance https://math.stackexchange.com/a/54108)
