14. AKS algorithm again..
1. Decide if n is a power of a natural number.
If so, go to step 5.
2. Choose (q,r,s) satisfying the hypotheses of the theorem.
3. For a = 1, . . . , s1 do the following:
(i) If a is a divisor of n, go to step 5.
(ii) If (鐃緒申鐃緒申鐃緒申 鐃緒申鐃緒申鐃緒申)鐃緒申鐃緒申鐃緒申 鐃緒申鐃緒申鐃緒申 鐃緒申鐃緒申鐃緒申 鐃緒申鐃緒申鐃緒申 鐃緒申鐃緒申鐃緒申鐃緒申鐃緒申鐃緒申鐃緒申鐃緒申鐃緒申 (鐃緒申鐃緒申鐃緒申 鐃緒申鐃緒申鐃緒申 1, 鐃緒申鐃緒申鐃緒申), go to step 5.
