Question: Let X = {1,2,3,4,5} and Y = {3,4}. Given a set P(X), power set of X, and a relation R, how many distinct equivalence classes

Let X = {1,2,3,4,5} and Y = {3,4}. Given a set P(X), power set of X, and a relation R, how many distinct equivalence classes are there? R: binary relation on P(X) such that (A, B), (), () is in if and only if = .

I wonder what the answer is.
