In a poly relationship with n members, there will be 2^n - n - 1 interpersonal relationships in play.
This is the cardinality of the power set of n, minus the number of singleton sets and the empty set.
Thought i would mention it, just in case you needed a quick way to calculate the number of relationships in ur polycule for ur therapist.
Rude. Our public schools are not great and numbers are scary. You’re being discriminatory.
