Primality proof for n = 5107:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=37.html>37 is prime.</a>
<br>b^((n-1)/37)-1 mod n = 33, which is a unit, inverse 4488.
<p><a href=23.html>23 is prime.</a>
<br>b^((n-1)/23)-1 mod n = 1868, which is a unit, inverse 298.
<p>(23 * 37) divides n-1.
<p>(23 * 37)^2 > n.
<p>n is prime by Pocklington's theorem.
