I brought up the range 250k-300k to the same level of WB (table A) already, now doing the same with 400k-430k.

Thanks! :smile:

I'm working with 4.0M-4.5M to 70 digits.

Looks like we're making nice progress toward completing all sequences <1M.

Checking the [URL="ftp://ftp.frontiernet.net/pub/users/Aliquot/public_ftp/AllSeq.zip"]summary[/URL], there are only 700 sequences at less than 100 digits in the DB and someone has already starting filling things in. Checking back on the shorter ones with an eye toward starting with the low-hanging fruit, someone beat me there.

For example, 357372:[code]Was: 357372 982. sz 66 2^2 * 3 * 5 * 11 * 1950367 * 20411983 * 2776371679 * 7226979377272886465246019587170635363203
Now: 357372 1293. sz 97 2^2 * 7 * 151[/code]

Do we need to make this an official project or shall we leave it open as a free-for-all?

RobertS was extending 300k-400k to 100 digits and said he expected to be done pretty soon. I'm extending 400k-500k to 100 digits and I don't think it will take more than a week or so to finish. So I don't think we need an official project.

[B]250,000-400,000[/B] are up to 100 digits
and now all files available in the DB!!!

That was almost true yesterday morning... now it really is. :smile:

Here are some stats and highlights from the 400k-500k range:

451 sequences extended to 100+ digits with a minimum 95-digit ecm'ed cofactor.

Four terminations (already reported):
478392: length 1567, max height 83
461430: length 2623, max height 100
471540: length 2177, max height 84
466560: length 2907, max height 97

One merge (already reported):
472836 reaches 99 digits, then decreases all the way to 150020.

Five sequences decreased to <20 digits (8 more <30 digits):
462474: min 9 digits
451506: min 10 digits
453798: min 11 digits
489216: min 12 digits
497214: min 15 digits

Six sequences extended by >2000 terms (15 more >1000 terms)
453798: added 5358 (:exclaim:) terms (min 11 digits): i8370 (size 120) = 2^2 * 7^2 * 547 * 673 * 46663 * c107
462474: added 3972 terms (min 9 digits): i4971 (size 100) = 2^2 * 7 * 5039 * c95
489216: added 3779 terms (min 12 digits): i5163 (size 104) = 2^2 * 3^2 * 7 * c102
451506: added 3755 terms (min 10 digits): i6012 (size 103) = 2^2 * 5 * 7 * 17 * c99
438966: added 2393 terms (min 38 digits): i3865 (size 104) = 2 * 3^2 * 29 * 41 * 43 * 919 * c95
469812: added 2187 terms (min 37 digits): i2952 (size 101) = 2 * 3 * c100

are you still working on 453798? Otherwise I'd like to reserve it.

I'm not, but I think unconnected has it reserved (see [URL="http://www.mersenneforum.org/showthread.php?p=240931#post240931"]this post[/URL]).

unconnected 2010-12-16 09:23

Great work, [B]bchaffin[/B]!
Do you have a script which generates this stats?

Yes, I've extended it to i8370. Now size 120 with 2^2*7^2 driver.
