Taking C191_139017523_29, ETA morning of Thursday 12 April

As long as nobody has previously asked for C217_67411_47 & It's not going to run for hundreds of hours on a 5960 X with 16 gig of RAM I also use for other things so it would probably need to fit in 9 gig tops I would be interested in taking. Thanks

Isn't that the same as?:
C191 from Phi_5(largest_factor(Phi_23(1009)))
Which I reserved on the previous page?

Not really, your number doesn't have a Phi_29 in the chain.

No, that number is C191_279xx283_5

Anything from the 14e queue should fit in 10GB and finish in less than 2 weeks. If you dodge the candidates with the largest assigned Q-range, you should be under a week and under 8GB. Matrix difficulty on 14e roughly correlates to Q-range sieved.

For example, I'm doing a GNFS-186 from the 15e queue, which fits in 9GB and will take 400hr running on half a 6-core i7. That's bigger than any job you should encounter on 14e.

Phi_3(Phi_5(Phi_5(Phi_3(Phi_5(3169)/5)/78049/22216443433)/1404522989938741)/5)/4052089 has been completed. I inadvertently used the file name in the title instead of the longer queue name here.

Sorry for the confusion!

The filename after the Cxxx for the Phi numbers confused me (I didn't make the connection with the digit representation). I now realise they refer to the first and last digits and the exponent is after the underscore...

So 27945714132675033142899109225439212386442031501005140283^5-1
becomes
279...283_5

I admit it, I'm a morron

Don't feel bad, I also ask what the file name is each time.
