Primality proof for n = 1335912079:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=6197.html>6197 is prime.</a>
<br>b^((n-1)/6197)-1 mod n = 255522159, which is a unit, inverse 108130948.
<p><a href=61.html>61 is prime.</a>
<br>b^((n-1)/61)-1 mod n = 338666802, which is a unit, inverse 412790218.
<p>(61 * 6197) divides n-1.
<p>(61 * 6197)^2 > n.
<p>n is prime by Pocklington's theorem.
