Beware! Downdriver hunters in sight! :smile:

(not me! I have no contribution to this sequence up to now, but I was thinking to reserve it when it will reach 83 digits and get some 2^3*3*5 driver, and the people/poachers will lose the interest... to grab it for myself and bring it back to 150 digits :smile:)

So, has the C114 been fully ECMd, or did whoever was running the sequence give up on it?

akruppa 2012-05-09 13:38

Looks like everyone was just hoping for an ECM factor. I start NFS.

[QUOTE=akruppa;298918]Looks like everyone was just hoping for an ECM factor. I start NFS.[/QUOTE]

Actually, I just came back from a meeting to notice that by accident I had left the computer running ECM on the number (I was hoping to get a lucky hit with a few curves). I ran 3k@3e6 + 1k@11e6... so yes, it should be ready for NFS.

akruppa 2012-05-09 19:23

Done. This was the first NFS factorization I've done in weeks that didn't get pre-empted by someone else. :smile:

i3307 c118 now. I did 300@3M so far. Others probably did a lot at 3M as well so I switch to 11M for now. Is anyone doing NFS already? If not I can take a shot at it.

Out of curiosity, what program does "everybody" (apparently except me) use to run 2k+ ECM curves?

Dubslow 2012-05-11 00:03

I use YAFU, [strike]which is really just an extra layer of code on top of[/strike] what akruppa said. Just use [URL="http://ecm.gforge.inria.fr/"]GMP-ECM[/URL], which is what everyone else uses.

akruppa 2012-05-11 00:07

YAFU is rather more than that but one of the things it can do is execute GMP-ECM for you.

bsquared 2012-05-11 00:50

I did the c116 on line 3328 (by NFS, via yafu), now working on the c116 of line 3330.

LaurV 2012-05-11 01:58

This graphic looks wonderful and amazing. It is going down so slowly, walking on tiptoes, like it is afraid of something, but still goes down. In my language we have an expression for it, how would you say in English when someone fart, but without any sound? Is it "sing"? (not like in singing a song, but like the air going out from a low pressurized pipe, without whistling). Or whisper? Like in the joke with blondes "what is this smell?", "sorry, I could control the noise, but couldn't control the smell...". This sequence is whispering its way down... Or this is a sung walk down (?!)

Dubslow 2012-05-11 02:05

The silent fart is not a thing of poetry, but a thing for which to don masks.

Whelp, we've escaped that, and along the way, ran across a 37^2 on line 3407. In the meantime, the DB has been conked out the last half hour or so, and it's [URL="http://www.downforeveryoneorjustme.com/factordb.com"]not just me[/URL].

Last I knew, we were at 3409:
2^3 · 937 · 7465504451<10> · 7318948406...61<102>
and my NFS just split the last one as
PRP57 = 198903918149090283322980891107642787318192482464665037007
PRP46 = 3679640137302425458160910470228581063166538023
and now I want to go watch a baseball game. So, if/when the DB fixes itself, that's where we left off.

Dubslow 2012-05-12 06:51

Since FDB still appears to be down, if no one complains in the next 20 minutes or so, I'll pick it up where I left it and run aliqueit overnight; if the DB is back by tomorrow (1600-1900 UTC or so) I'll upload the work and go back to regular work continue as usual.

whatever which I get that way is being the following, the follows, as such, away

By the same way,

[/CODE]
The factorDB problem seems to be with querying with the following
(above mentioned) number only, actually
So, thus
thereby what iteration from the aliquot sequence (314718) is being the
(this) number itself, rather
c116 = id1100000000508647107


[QUOTE=schickel;298757]Was that on purpose?[/QUOTE]
What lasted for only 3 lines - "Batalov" had actually called it to be a suspense. To keep it a mystery furthermore, I put it into the multiple nested code boxes, as such. The fact is being that following it,
you should have quite directly, automatically known to have scrolled down that code boxes already,

@ Batalov - "Creyaufmüller" hasn't received your result from the sequence 345324" rather

By the way,the fact that
[I]314718 > i10000 [/I] the same thing
is being [I]true[/I]?
by now itself

Raman 2012-05-12 15:36

For the other numbers, aliquot sequences
the factorDB works out to be fine enough for me
although

Let alone for the sequence this aliquot 314718,
that factorDB is being a problem Alone solely
mainly due to the value for
c116 = id1100000000508647107
due to a duplicate entry from the occurrences from the "unique" Primary Key field

For the following number, aliquot sequence 9298091736
has escaped from a 2*3 driver, factor out number
9298091736 completely in order to know about
the secret behind this number, the around this fact

98415 = 5*3[sup]9[/sup]
972 = 4*3[sup]5[/sup]
9565938 = 6*3[sup]13[/sup]
94143178827 = 9*3[sup]21[/sup]
9298091736 = 8*3[sup]19[/sup]
903981141 = 7*3[sup]17[/sup]

98415 = 98304 + 111
98415 = 5*3[sup]9[/sup]; 98304 = 3*2[sup]15[/sup]

2[B]48965[/B] * 3 = 7[B]46895
[/B]

rajula 2012-05-12 15:47

Even if the sequence is currently broken in the DB, we could continue putting the factors there by starting beyond the breaking-point; for example from [URL="http://factordb.com/sequences.php?se=1&aq=40957875574394316311003047843043516950271720473684192538168111457395057835508589937432267551919865595270070289148056&action=last20&fr=0&to=100"]this iteration[/URL]. (I hope I got the right number to start from..)

So, how about it, Batalov. :whistle:

...so you think it is a good thought to insert into a database that is being repaired? You will be inserting into "[URL="http://en.wikipedia.org/wiki/Write-only_memory"]write-only memory[/URL]" :-)
If Syd made his DB conventionally, then there are (at least) two instances, production and test (which will be flipped when one is repaired and then sync'd).

Inserted a few more lines, but don't be surprised when they will be gone after the database repair.

P.S. And there, Syd figured that he left a door open for you. It is now shut.

Anyway, it is line +101, a c95.
In line +109, a c109. Running NFS.

Why are you doing gnfs on a c90?

Batalov 2012-05-12 23:37

Because it takes equal amount of time, maybe slightly faster by gnfs.

bsquared 2012-05-12 23:41

Do whatever is faster for you - it just surprises me that c90 is faster by gnfs. For me on intel chips, the crossover is more like c95, even with asm ggnfs.

Thanks!

This is not about attaching every fart, but about trying to reconstruct / collect the missing parts to stitch the parts together. We don't know when (and to what extent complete) the sequence will be back in the database again...

Batalov 2012-05-13 06:22

I can kinda agree with that. [I]Even though[/I] my own estimate that this will be very soon and doesn't warrant ...ehm... (I've already been rude, so I'll try to choose words more temperantly) ... ok, I'll call this hoarding.

Like not throwing away credit card receipts (worse yet, make copies of these) -- because there could be a mistake in billing. On one hand, yes, true, this can happen and did happen on my memory once or twice in ten years. On the other hand, one's home starts looking like a pawn shop or a dashboard of some cars.

I think we should boldly trust the database.

P.S. Clarification: I mean, we should have some diligent footprints of our computations stored somewhere in own archives (e.g. I believe that I have > 10[sup]4[/sup] ggnfs.logs and polys for hundreds of aliquot sequences, and dozens of memorable C/Hom.C./etc snfs polys, again e.g. my beloved octics); -- just not on the forum.

as at last, lately[/QUOTE]

This was being the last number that I had seen line, the thing that I had been written much before.

It should have been 314718: i9823 NOT i9869 at all

The lines corresponding to 314718: i9823 THROUGH i9869 are being missing out

314718: i9823 would seem to have been corrupted within the factor database meanwhile

Does that mean the lines following i9823 would mutate leading to wrong subsequent result iterations,
incorrect values for the lines beyond the line 314718: i9823 which is being after the following line
that is being given away into
id1100000000508647107 -> id1100000000508756358 = 2*c116

akruppa 2012-05-13 18:21

I haven't found many factors over the last few days, and haven't kept any of them as they usually were relatively small ECM factors. I remember one p51, but I haven't kept that one, either, since someone else had already submitted it.

Edit: I had an old .elf file, but it had data only up to i2998. That part agrees with an .elf file I just downloaded. I had two pages with factorizations left in my brower cache, but the factors appear in 4788.elf or 409578...8056.elf so they are not from the missing part.

I am bowing out at +1398, c112. Put one line in your elf file and you can go with aliqueit -e
[CODE] 1397 . 1001777285392569572904290646390787226308237439383461254469983491988408403137367200479555518410377674168016748413824068285936 = 2^4 * 31 * 1447 * 18103888892349677 * 1922571138731027507 * 334759903278150757688691430026991 * 119793497488326129606597958143119427551092583328047
[/CODE]

I'll run the c108 for closure.
