Primality proof for n = 3761:
<p>Take b = 3.
<p>b^(n-1) mod n = 1.
<p><a href=47.html>47 is prime.</a>
<br>b^((n-1)/47)-1 mod n = 2689, which is a unit, inverse 1463.
<p><a href=5.html>5 is prime.</a>
<br>b^((n-1)/5)-1 mod n = 2743, which is a unit, inverse 1947.
<p>(5 * 47) divides n-1.
<p>(5 * 47)^2 > n.
<p>n is prime by Pocklington's theorem.
