We have a C123. Serge, is this yours?

Batalov · 2009-08-13, 09:55

No. Not taking.
And no. Not mine - someone, probably Ben, found a p36 factor, so it is ECM'd quite enough. I did add some curves but no luck (I must have spent it elsewhere).

bsquared · 2009-08-13, 12:49

I can't claim the p36... it was all I could do to post the factors before heading off to bed.

But I'll take the C123 unless someone else really wants it.

bsquared · 2009-08-14, 13:06

Seems I can't put these in the database right now... could someone do that when it comes back up? I'm leaving for a few days and won't be able to.

Code:

prp54 factor: 162987771789684258473910202934761456347012754686995779
prp70 factor: 3476459109608271666227966958815165533599668181825613725957567035782921

thanks,

Sure thing.

Anyone know what comes next for 4788? I don't have 4788's elf or the other cofactors in this line.
Edit: I noticed that the data from Greebley ended at 2427. I put in the factors for the C150 from 2428, but can't break the c133 on the next line very easily (it ran a few runs at 250k with no success, and I didn't want to waste too much work when someone probably had the data somewhere).

The last c150 was part of a 2^5*3*c150. You can find the details from the relevant thread. I don't know how many other lines where there before the c123

The c133 was p41*p92. The next line was small factors*p36*the c123. Ben, wanna have a crack at these to find the values of p41 and p36? (I remember the digit lengths, but not the numbers)

with

Code:

c142 = 7155182203298369448937942346165428347449795593016786201865194819149797582908139440202912832303431350932284942688546565074936912797117840985577

The c142 has had hardly any ECM, so may have factors below 25 digits.

The c142 has had 74 curves@11e3 and 53 curves@5e4 with no success. I'm not working on it more right now.
Edit: 10metreh beat me to it, and with about as much ECM. Oh well.
