Comment:
I just committed some initial work.
There are a couple things I'm not happy about at the moment:
- the change on line 18772 of generic_graph.py from
{{{G.relabel(return_map=True)}}} to
{{{GenericGraph.relabel(G,return_map=True)}}} was made due to the
conflicting definition of the relabel function in !DynkinDiagram. I tried
to get around it by converting !DynkinDiagrams to !DiGraphs, but somehow I
couldn't make it work. If there's a better way, please let me know.
- there's some index set weirdness that I got around in finite type as on
line 275 of cartan_matrix.py, but it feels hacky and I would like a better
solution.
