Ticket #26851 – Description
initial v1 1 This change is not without consequences. Indeed, when adding vertices inthe graph `G` resulting from the union of `self` and `other`, the order in which vertices are added to `G` fixes the ordering `list(G)`.1 This change is not without consequences. Indeed, when adding vertices to the graph `G` resulting from the union of `self` and `other`, the order in which vertices are added to `G` fixes the ordering `list(G)`. 2 2 3 This change breaks the graph generator `EllinghamHorton54Graph` that uses several times `disjoint_union` which itself calls `union`. Also, we change the generator to something simpler and more robust.3 For instance, this change breaks the graph generator `EllinghamHorton54Graph` that uses several times `disjoint_union` which itself calls `union` and that uses the ordering of `list(G)` to relabel vertices. Also, we change the generator to something simpler and more robust.
