Primality proof for n = 10957:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=83.html>83 is prime.</a>
<br>b^((n-1)/83)-1 mod n = 1834, which is a unit, inverse 10724.
<p><a href=11.html>11 is prime.</a>
<br>b^((n-1)/11)-1 mod n = 10438, which is a unit, inverse 7368.
<p>(11 * 83) divides n-1.
<p>(11 * 83)^2 > n.
<p>n is prime by Pocklington's theorem.
