Done here:

  • correct method eulerian_orientation for graphs without edge (was not using the right set of vertices)
    • Should we move this method to ?
  • some care in min_spanning_tree, but we have remaining issues:
    • algorithm "Prim_fringe" compare vertex labels. I added hash(..) around, but this is certainly not enough.
    • the output of min spanning tree methods is sorted. As said in #26547, there is no reason for that.
  • avoid a call to .edges in cycle_basis

Is there a metaticket for files in graphs? I'm particularly interested in more on, especially is_isomorphic, and also base/sparse_graph.pyx, especially iterator_edges. Both of these try to sort vertices, which cause Python 3 doctest failures in homology/ and homology/

Let us use #26640 as meta ticket. Should have been opened earlier. Feel free to modify it as I don't know how to organize it.
