Chapter 8 Exercise 10

This software determines the order of , where p is a prime less than 71. Run the software for p = 3, 5, 7 and 11.

What is the highest power of   p that divides the order? What is the highest power of   p-1 that divides the order? Make a conjecture about the order of for all primes p.
