Primality proof for n = 16451:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=47.html>47 is prime.</a>
<br>b^((n-1)/47)-1 mod n = 5824, which is a unit, inverse 1144.
<p><a href=7.html>7 is prime.</a>
<br>b^((n-1)/7)-1 mod n = 2450, which is a unit, inverse 11744.
<p>(7 * 47) divides n-1.
<p>(7 * 47)^2 > n.
<p>n is prime by Pocklington's theorem.
