Primality proof for n = 102330720522739:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=245161069.html>245161069 is prime.</a>
<br>b^((n-1)/245161069)-1 mod n = 76708486521724, which is a unit, inverse 12005238975439.
<p>(245161069) divides n-1.
<p>(245161069)^2 > n.
<p>n is prime by Pocklington's theorem.
