Total ECM done so far (dekcarki + unconnected + Andi47 + others at B1<11e6):

~1600@1e6
2129@3e6
1617@11e6
512@43e6

This sums up to @88.8% of t45 or 12.9% of t50

I certainly never imagined that there would be enough interest (and horsepower) to push this sequence up to 170+ digits. Here's hoping that we can keep this going for at least a couple more digits!

PS. Countdown to 9000 lines for 314718: 34 lines!

That means only 1034 lines to 10000, 10metreh!

Well we could reach 10000 lines if we get the downdriver

I also thank everyone for all the CPU cycles you have contributed to a project whose aim is just to have fun.

I hope that within the next nine months, among other things, we will find a sequence that merges with itself and forms a really long cycle. That would break a record that is over 90 years old!

I'll launch another 1000 curves @B1=11e6.

unconnected · 2010-01-04, 15:21

After ~300 curves I got p45 factor.

Code:

Factor=515906718700780232747489355180421058695246643  Method=ECM  B1=11000000  Sigma=3903608469

Cool! I had 280 or so of 1200 curves at 43e6 completed which I'm now killing.

R. Gerbicz · 2010-01-04, 16:11

Factored the next step:

Code:

Using B1=1000000, B2=1045563762, polynomial Dickson(6), sigma=3593314410
Step 1 took 12230ms
********** Factor found in step 1: 2927046619584909196431045775337

Have you sent that to Paul Zimmermann?

unconnected · 2010-01-04, 16:45

No, it is too small for me. Last year I have had two p57 and several p50+ factors.

Why not get on the top 10 for a few days?

We now have 2^6, and we can't lose it this line.

R. Gerbicz · 2010-01-04, 19:18

Completed 900 curves (on three cores) on c163 at B1=1e6 so t35 level. Doing no more work.

With my normal 'overkill is barely adequate' policy, I have started 2000@4e7 on the c163. This will take about 24 hours.
