If you're interested, here's the information for our given RSA encryption:

I'll mess around a bit more with the code on uni's computer tomorrow.

I got so far as to figured out the e-score(?) is the 10^-13 one in .dat.p file; "rroots" is probably the number of real roots of the polynomial, and that smallest integer param is a good indication of progress.

I'm progressing but struggling quite a bit understanding the ggnfs-doc.pdf, as I barely know any group theory. On the bright side, I'll have a quite a head start next year

Again, thank you everybody for the information!
