Primality proof for n = 49290007066067:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=10882031.html>10882031 is prime.</a>
<br>b^((n-1)/10882031)-1 mod n = 47170788343676, which is a unit, inverse 28702818375219.
<p>(10882031) divides n-1.
<p>(10882031)^2 > n.
<p>n is prime by Pocklington's theorem.
