Primality proof for n = 60477271182120907:
<p>Take b = 2.
<p>b^(n-1) mod n = 1.
<p><a href=1458566971.html>1458566971 is prime.</a>
<br>b^((n-1)/1458566971)-1 mod n = 35912749431528278, which is a unit, inverse 11353171055635145.
<p>(1458566971) divides n-1.
<p>(1458566971)^2 > n.
<p>n is prime by Pocklington's theorem.
