Primality proof for n = 204061199:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=3769.html>3769 is prime.</a>
<br>b^((n-1)/3769)-1 mod n = 58449174, which is a unit, inverse 108819925.
<p><a href=107.html>107 is prime.</a>
<br>b^((n-1)/107)-1 mod n = 116529308, which is a unit, inverse 70558875.
<p>(107 * 3769) divides n-1.
<p>(107 * 3769)^2 > n.
<p>n is prime by Pocklington's theorem.
