so simply modifing the #define in gnfs.h produces the above error. I also note that in get_polyval(...), cases for poly degree > 6 do not exist. I'm pretty sure it would be non-trivial to add the necessary code to make the library work with degree > 6, and of course I am not trying to tell you to do so... just FYI.

Both of those code blocks need each other; there is a similar check on the polynomial degree for the factor base generator. Both can get worked around with poly-degree-independent code, but I think it probably isn't worth the effort.

If I can help, let me know.

Thanks for the offer; when I get time to study it more I'm sure I'll have more questions.

I now have a matrix for 2,799+

which is bigger then what I was hoping to work with and definately could benefit from more sieving, but my sieving resources will be tied up on 2,1598L, so it'll have to do.

ETA on 2 cores of a Quad Core X5365 is about 6/24/08.

GNFS-165 is a nice kind of size, the matrix ought to fit in 4GB and a sieving time of a couple of CPU-years fits a number of combinations of patience and CPU-availability. Go for it; I only wish the GNFS-record-table kept by Sam Wagstaff had a few more entries on it so you could stay on it longer.

Paul (xilman) just finished the LA for 2,1538M C208 = p80.p128 [thanks!]

p80 = 43125229216737082272194634000839865996208236725833746045943422097093188432757397

3,517+ will finish Friday evening. 10,247+ is about 40% sieved.
