Primality proof for n = 1206941:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=233.html>233 is prime.</a>
<br>b^((n-1)/233)-1 mod n = 445776, which is a unit, inverse 66916.
<p><a href=37.html>37 is prime.</a>
<br>b^((n-1)/37)-1 mod n = 185486, which is a unit, inverse 793173.
<p>(37 * 233) divides n-1.
<p>(37 * 233)^2 > n.
<p>n is prime by Pocklington's theorem.
