Exercises 52 and 53, R n refers to the family of equivalence relations defined in Example 5. Recall that s R n t, where s and t are two strings if s = t or s and t are strings with at least n characters that agree in their first n characters. 52. Show that the paron of the set of all bit strings formed by equivalence classes of bit strings with respect to the equivalence relation R 4 is a refinement of the partition formed by equivalence classes of bit strings with respect to the equivalence relation R 3 .
