Back story: Weib Bosma had a note on his site about 314718 merging with 16100. Further research revealed that 314718 actually merges with 4788:
Code:
314718.elf:i6466 = 4788.elf:i6 = 60564 Christophe Clavier has been working on 4788 and had it at line 2335 stalled on a c131. Factoreyes ran an NFS job for me and cracked it as p46*p86. I managed to run ECM jobs on lines 23362349. Presently I am on line 2350 with a c114 that has had 120 curves at 43M. Since I am booked up on my NFS resources, I want to pass this job off to someone else that can tackle it easier than I can. Let me know if you want to take over 4788 or just tackle the c114 and pass 4788 back to the forum.... The c114: Code:
333969874513396811666453580618603759213027599438507119081627586159016823042831267378101968786698031498425405759447 modedit: Link to sequence 4788 in the database. Last fiddled with by henryzz on 20160611 at 14:22 Reason: Changed link to factordb rather than the old version and moved the 3408 link
