WebAnswer. The element in the brackets, [ ] is called the representative of the equivalence class. An equivalence class can be represented by any element in that equivalence class. So, in Example 6.3.2 , [S2] = [S3] = [S1] = {S1, S2, S3}. This equality of equivalence classes will be formalized in Lemma 6.3.1.
