SUMMARY
The discussion centers on proving that the order of the element x^k in a group of order n is n/d, where d is the greatest common divisor (gcd) of n and k. The participant establishes that (x^k)^(n/d) = 1, indicating that n/d is a valid order. However, they seek to confirm that n/d is indeed the smallest order, exploring the implications of assuming a smaller order s < n/d and its relationship to n/d.
