Re: A new and largest-known prime number has been discovered!

That's pretty awesome stuff - especially that you did the math and programming yourself (not just running GIMPS on your home PC).

Btw, what is the "799167/" in the 6th entry? Is that the first six digits of the very long coefficient? That prime is interesting because even in its collapsed form it still requires a lengthy expression.

Yeah that was another "show off" thing I did. The coefficient is so large, it could not fit on one line. So I generated a large Payam Number for Base-2, and generated a power of 2 prime using 799167535... as the coefficient. Basically is was 2 raised to the power of 1.2 million, times that large coefficient, minus 1.  I think it's the largest coefficient ever used to calculate a prime.

Payam Numbers are explained here:

That's why I did that stuff. I still own the record for the prime containing the greatest number of zeroes. If you think about it, the number is "mostly nothing."


By the way, GIMPS stands for the Great Internet Mersenne Prime Search. That only works for 2^n - 1 = prime. None of my numbers take that form, so therefore, I could not have been using GIMPS.
