Hello !!! I always have to include in my graphs functions some part of code to deal with the fact that for undirected graphs edges can be returned as (u,v) or as (v,u), which my code does not like.... Isn't there a Sage a type of variable which is both immutable and not ordered ?
I'd love to have something like Set(u,v) but I also need it to be immutable, hashable, etc... ;-) Thank you !
