2+ table - Page 9

This completes the even*even 2+ to 900 bits. Congratulations!

Now we need to push the 2LMs and 2+ odds.

There's an easy one in each of those tables that you can start with.

Words to live by!

Actually, Paul Z. recently took down the easy 2+ odd one by ECM. Oh well.

If I've counted right, there are only four 2-odd numbers left below 900 bits, 2,881+, 2,887+/-, and 2,899-. After clearing the remaining wanted numbers, it might be a worthwhile goal for NFS@Home to clear these.
________

That's right: 2 in the process, and 4 more; all good for 2³¹ lims to save space on your mighty server (and traffic; I wonder when it will start looking like a constant DDoS attack on Fullerton :-).

2^nd EDIT: 2,899-, missed it, too. 2,889- would have been easy, but it's been done for ages.
Easy 2,889+ killed by Paul.

And the easy one on 2- odd is the one with exponent divisible by 7?

I see that CWI have reserved 2,881+.

Must be time to stop ecm's then. Not that there's likely to be
anything within range ... -Bruce

(The other three are on the last few 100 curves.)

Here is 2,1128+ c200 = p84.p117

p84 = 138283721500695845774122794906574976887904939982079412885536147948742638438410963841

2,1149- is about 70% sieved. I will do 2,1161+ next.
Please reserve it for me.

A request to Serge:

Can you provide a bit more information than what is given on Sam's
reservations page? What numbers are you and Bruce actually sieving?
Which ones are running LA? Which ones haven't you started? etc......

In the week since M941 finished sieving we've done two, counting
2, 1646L that's just finished. Also 2, 1654L is in filtering; and 10, 248+ is
sieving now. That will complete our second round of seven reservations.
Just from easy numbers. None of our hard numbers (since we finished
2, 2086M) have started, 11M583, C180 gnfs, 3m551. I expect that
we'll clear a few more small ones soon. -Bruce

Batalov · 2009-11-30, 19:50

After those numbers that Bruce mentioned, in the sieving pipeline are the "easy" 1st holes 11,241- 12,247-, the 2nd hole 3,559+ and the forth hole 6,371-. The preference was recently given to wanted numbers, while the large numbers can wait (they are not in the wanted list).

Wait, the wanted list was just updated and 3,551- is now wanted. We will probably continue with it after the above numbers.

Notably, unassigned from the wanted for page 111 list, there remained three C160 gnfs and just one snfs number 7,311- C225 (diff.263.6). Everything else is done or close to be done.
