Primality proof for n = 3529:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=7.html>7 is prime.</a>
<br>b^((n-1)/7)-1 mod n = 2223, which is a unit, inverse 127.
<p><a href=3.html>3 is prime.</a>
<br>b^((n-1)/3)-1 mod n = 447, which is a unit, inverse 3379.
<p>(3^2 * 7^2) divides n-1.
<p>(3^2 * 7^2)^2 > n.
<p>n is prime by Pocklington's theorem.
