Primality proof for n = 60757:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=83.html>83 is prime.</a>
<br>b^((n-1)/83)-1 mod n = 37315, which is a unit, inverse 47417.
<p><a href=61.html>61 is prime.</a>
<br>b^((n-1)/61)-1 mod n = 12714, which is a unit, inverse 41599.
<p>(61 * 83) divides n-1.
<p>(61 * 83)^2 > n.
<p>n is prime by Pocklington's theorem.
