Primality proof for n = 5662229:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=521.html>521 is prime.</a>
<br>b^((n-1)/521)-1 mod n = 3212052, which is a unit, inverse 1564518.
<p><a href=19.html>19 is prime.</a>
<br>b^((n-1)/19)-1 mod n = 4134036, which is a unit, inverse 3088404.
<p>(19 * 521) divides n-1.
<p>(19 * 521)^2 > n.
<p>n is prime by Pocklington's theorem.
