Primality proof for n = 4537129159:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=28771.html>28771 is prime.</a>
<br>b^((n-1)/28771)-1 mod n = 4037130531, which is a unit, inverse 4344480992.
<p><a href=8761.html>8761 is prime.</a>
<br>b^((n-1)/8761)-1 mod n = 2369722005, which is a unit, inverse 4416811106.
<p>(8761 * 28771) divides n-1.
<p>(8761 * 28771)^2 > n.
<p>n is prime by Pocklington's theorem.
