If the edge labels of the original graph matter, then I am not sure this will work, because no option seem to exist for taking into account vertex labels in the automorphism group.

If In most cases this group coincides with the edge labels of the original graph matter, then I am not sure this will work, because no option seem to exist automorphism group, with some exceptions (see for taking into account vertex labels in the automorphism group.instance https://math.stackexchange.com/a/54108)

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

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