The **52** equivalence relations on a 5-element set depicted as 5×5 logical matrices (colored fields, including those in light gray, stand for ones; white fields for zeros.)

Equivalence Class: Definition. An equivalence class is the name that we give to the **subset of S which includes all elements that are equivalent to each other**. “Equivalent” is dependent on a specified relationship, called an equivalence relation.

In math, two sets are said to be equal **if they contain the same number of elements** and also the same elements though the order of elements in the two sets may be different. So {a, b, c} and {c, b, a} are called equal sets. Equivalent.

Definition An equivalence relationon a set S, is a relation on S which is reflexive, symmetricand transitive . Examples: Let S = ℤ and define R = {(x,y) | x and y have the same parity} i.e., x and y are either both even or both odd. The parity relation is an equivalence relation.
