SNFS polynomials.
I had a look at the SNFS polynomials generated by factordb and noticed it generates very bad ones. Eg: http://factorization.ath.cx/index.ph...00000487178750 which is (14754135833^11-1)/132772468352168 gets:
Code:
n: 54317968970751484973310399914288545196091168576179094060078804933353377706605252225479726219559637 m: 217684524178614603889 deg: 4 skew: 0 type: snfs c4: 3211747038473252619535796054537 c0: -1 rlim: 343800 alim: 343800 lpbr: 25 lpba: 25 mfbr: 45 mfba: 45 rlambda: 2.2 alambda: 2.2 And http://factorization.ath.cx/index.ph...00000479069951 which is (6638^31+1)/2316174361302856299249 gets: Code:

it's auto-generated, give it some slack!
I think that the original idea was more like to give an idea of what the snfs poly should look like. |
