Primality proof for n = 29611:
<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 = 18053, which is a unit, inverse 22353.
<p><a href=5.html>5 is prime.</a>
<br>b^((n-1)/5)-1 mod n = 22691, which is a unit, inverse 8434.
<p>(5 * 47) divides n-1.
<p>(5 * 47)^2 > n.
<p>n is prime by Pocklington's theorem.
