Primality proof for n = 6299:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=67.html>67 is prime.</a>
<br>b^((n-1)/67)-1 mod n = 4252, which is a unit, inverse 4505.
<p><a href=47.html>47 is prime.</a>
<br>b^((n-1)/47)-1 mod n = 1576, which is a unit, inverse 5040.
<p>(47 * 67) divides n-1.
<p>(47 * 67)^2 > n.
<p>n is prime by Pocklington's theorem.
