Yes, CRG, even 3 * p10000 will be accepted into either Special or General cofactor.

10^10000 + 336030 = p1 . p1 . p10000, see http://oeis.org/classic/A142587

You go a long way to try and use your methods.

@CRG: Now, I will truly congratulate you if you can give me a p(10^6) cofactor.

Oh, right: 3 * (2^43112609-1)?

Clearly, you have no appreciation for my minimalism. I would choose
3481 · 2^6816832 - 59 · 2^3408417 + 1.

You tend to choose simple expressions. Why the sudden change of heart?

3.14159 · 2010-08-29, 02:48

Also: I'm sieving for k * 15661¹⁵⁶⁶¹ + 1

P.S: Dammit, guys. You could have helped out with the searches.

Sieved to 1.63 * 10¹² for k * 13751¹³⁷⁵¹ + 1

Bigger number, smaller cofactor (while still being at least a million digits).

3.14159 · 2010-08-29, 03:04

Okay: For now, I'm going to be sieving. I have finally convinced myself to look for larger primes, optimally in the 30-70k digit range.

I have a 56300 and 65700 prime-based k-b-b search.

Okay; Mods? No assistance? Come on, toss me a bone here!

3.14159 · 2010-08-29, 04:05

Well, in the meantime... A General Cofactor is coming up.

Exactly what kind of assistance are you looking for from the Mods?

Some assistance with the searches.

By mods, I mean, the mods that visit here the most often. (Karsten, etc.)

Also from other regular members.
