let's consider the equivalence relation A∾B if and only if A-B is evenly divisible by 4. So 0∾4 is true and -86∾2 is true, and so on. We can make four "equivalence classes" where every integer is in exactly one class, and every integer in ...
That is not the canonical item associated with the equivalence class that contains -123; that canonical item is 1. It's important to remember this fact when doing things like balancing a hash table: int bucketIndex = item.GetHashCode() % bucketCount; or determining if a number is odd: ...
