I've got enough open work to do and will not waste my CPU-time for the search of lonesome 70k-digit primes unless they'll close some holes or new n-ranges in my [url=www.rieselprime.de]Riesel DataBase[/url]!

yeah I may only do factoring as what I was given as dates says lucas lehmer test for one exponent wouldn't finish in almost 4 years.

Could have just said, "No, thanks, I'm busy."

This was unnecessarily rude.

Also: Since you're not willing to aid in the search for smaller prime numbers: Would you be willing to aid in the search for a 257920-digit prime?

No, thanks, I'm busy.

What range are you working on at the moment?

Sieved up to 1.467 * 10[sup]12[/sup] for k * 15661[sup]15661[/sup] + 1. Approximately 1 in 25 candidates are remaining.

Most of what I am going to do is sievework, for now.

The next three searches are going to be prime k-b-b searches, or item 15.

Maybe I will look for item 16: Number, square, and fourth.

The smallest example = 2:

3, 5, 17.

Followed by 4: 17, 257, 65537.

This is the one that amuses me the most. You could use a nice sieve for this form.

I wonder how that would work...

Oh. Right. kmin, kmax, multiplier(n), pmax.

What's your record for that form, anyway?

[QUOTE=3.14159;227513]I wonder how that would work...

nmin, nmax, and pmax I'd think. You only have one variable in the expression... right?

Number, square, and fourth? 211 digits, for the largest number, the fourth power.

I normally choose the multiplier and k-range.
