(a) That sequence (2") appears to repeat after a few initial terms. Why must such repetition occur for every m? (b) Let p(m) be length of the "tail" of terms that occur before the repeating part begins. For instance, p(10) = 0, p(28) = 1 and p(48) = 3. For which m does p(m) = 0? When does p(m) = 1? When does p(m) = 2? (c) Let o(m) be the period (length of the periodic cycle) of the sequence (2") in Zm- For instance, o(10) = 4 and o(28) = 3 and o(48) = 2. How is o(m) related to o(2m)? What about o(m) and o(3m)? How is o(35) related to o(5) and o(7)?
