Multi partnered? Do you mean polyamorous? I know several friends who are polyamorous, it works well for them

That relationship would be interesting but solely from a Combinatorics perspective.

It would be pretty simple, actually, as everyone would be part of the same set. Polyamorous relationships where several people have multiple none-shared partners gets way more interesting. I am not sure I could cope with keeping track of it if I were in the middle of it though.
