Was that a complete search with GGNFS?
Here's a nice one that popped out of msieve, searching around the higher than default leading coefficient (to not potentially waste effort).
It has a smaller 'e' value but sieves ~4% faster.
Code:
# norm 2.230278e-13 alpha -6.709216 e 2.485e-11
skew: 508389.51
c0: -1715096044102766131555640234382300
c1: 72526691734251272118367460690
c2: -120771683611520445554704
c3: -483822867366235288
c4: 398591914077
c5: 876240
Y0: -198414717006063417277428937
Y1: 3937215344981633
Using the params:
Code:
rlim: 9000000
alim: 9000000
lpbr: 28
lpba: 28
mfbr: 56
mfba: 56
rlambda: 2.5
alambda: 2.5
The GGNFS poly: total yield: 15570, q=10010023 (0.02606 sec/rel)
msieve poly: total yield: 17086, q=10010023 (0.02513 sec/rel)
