For the set X={m,n.p,q,r,s}, let R be the relation on P(X) (power set) given by A R B iff A and B have the same number of elements. List all the elements in {m}/R (equivalence class); in {m,n,p,q,r,s}/R. How many elements are in X/R? How many elements are in P(X)/R?

List the following elements in proper set notation. Place the elements in numerical order within the set.
* 0
* 1
* 123
* 4
* 34
