It doesn't have to be a particularly noteworthy factor for Stargate to be fond of it. (Re-read the thread title.) Now, if we start adding sub-64-bit factors here, that may be crossing the line.

I would have guessed the opposite. On bad hardware, Gerbicz should catch more errors than Jacobi (key word is catch; the actual number of bad iterations should be roughly equal either way), but also...

I don't think a double (53-bit mantissa) is enough precision for that number, and even a long double on x86 (which I believe gives you the 80-bit x87 extended-precision float, with a 64-bit mantissa)...

AFAIK gwnum and Prime95/mprime have the same license. I don't see a license file in the gwnum source folder, but both LLR and OpenPFGW (which both link gwnum) reference similar terms.
