Primality proof for n = 6730519843040614479184435237013:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=8464734851.html>8464734851 is prime.</a>
<br>b^((n-1)/8464734851)-1 mod n = 3681886084939357546404908796125, which is a unit, inverse 3039756709910638621157556372474.
<p><a href=671065561.html>671065561 is prime.</a>
<br>b^((n-1)/671065561)-1 mod n = 5255658239705769014805159091582, which is a unit, inverse 3086872343501381515492565796044.
<p>(671065561 * 8464734851) divides n-1.
<p>(671065561 * 8464734851)^2 > n.
<p>n is prime by Pocklington's theorem.
