Thanks for the comment!. The use case was to keep unique permutations of some set and then compare them pairwise or something like that. I like the idea of a long string, I'll try to apply it.
so rather than storing a full set you can store ids for the permutation like a vector of idsr: 1, 2, 3, 4, 5: and then another vector with 5, 4, 1, 2, 3... etc.

Good idea, thanks!
happy to see results, if that's faster and how :)
