If you can do one every 10 nanoseconds, That gives you 10**192 seconds, or around 10**175 ages of the universe. That to check a single number.

Yikes! And you know my professor said that the smallest possible starting point would be two numbers of 10**200. At least this is what I gathered from our conversation. Is that right?

Math::Pari is very good for number theory kind of things.

I'll have a look at that when I get home from school here. Thanks for the tip.

I'm still pretty lost here. I don't know where to start.
