I've found the following poly (9 hours msieve-gpu searching): Code: n: 206291417462093576497275239580773052795596055350565606087502662805051224044201602337850673455835775692863740037805407606265476824913591751307682500480113600344276700606001 # norm 1.306001e-16 alpha -8.871987 e 2.977e-13 rroots 3 skew: 162345250.84 c0: -577062733978460861005241440490749355102976512 c1: -12260826936151352820546357994499780916 c2: 178538325918319471247024945044 c3: 958590300841474414947 c4: -4423011255032 c5: 11844 Y0: -1770910298352749710979419014235215 Y1: 613792628360770487 type: gnfs The record e-score for 171 digits is 3.730e-13 so this is not too bad for a first try. If Max could see if he can spin it up I would be very grateful. Also is anyone interested in 24^179+1 ? If not I'll put it through NFS@Home in a week or so. Chris
