Ryan is running ECM on C301_143_129, with some 10k curves @B1=76e8 completed so far. He is planning on running another 16k curves soon, at which point it may be safe to declare victory and flee the field.

BTW, 142[SUP]139[/SUP]+139[SUP]142[/SUP] is the only number without known factors :)

Ryan is running ECM @B1=76e8 on this number, as well as C301_143_129. 16k curves at a time (alternating between the two composites). No luck so far.

Not sure how many curves are required at this level before declaring both numbers "NFS ready", but I'm thinking we are rapidly approaching that point.

Ryan has started sieving this number.
