Primality proof for n = 912026155762311229:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=16064717743999.html>16064717743999 is prime.</a>
<br>b^((n-1)/16064717743999)-1 mod n = 813929617109191379, which is a unit, inverse 371448305354204680.
<p>(16064717743999) divides n-1.
<p>(16064717743999)^2 > n.
<p>n is prime by Pocklington's theorem.
