Thanks Paul. I was particularly pleased with my hand-crafted sieve,
which involved solving first a quadratic and then a discrete logarithm problem.

Mind you, I still only sieved out prime divisors less than a few billion.
But at least I never had to use the mindless -f flag for pfgw.

David (ever a light, if still canny, siever)
