What are the equivalence classes of the bit
Chapter 8, Problem 8.5.33(choose chapter or problem)
What are the equivalence classes of the bit strings in Exercise 30 for the equivalence relation R4 from Example 5 on the set of all bit strings? (Recall that bit strings s and t are equivalent under R4 if and only if they are equal or they are both at least four bits long and agree in their first four bits.)
