Shouldn't that be 2*3?

Sweet! Hang in there... My own downdriver in 128370 is just on its 30th line. Takes a while up at c120... I'm hoping to come loose soon and swoop down on 1.

 2009-04-13, 20:04 #50 KriZp     Feb 2007 33·5 Posts yes, it was quite exciting coming back since I lost SSH access to the computer running the sequence last tuesday, and couldn't check untill a few hours ago. I'm out of GNFS territory now I suppose, so things should hopefully move quicker! Schickel (somewhat surprisingly to me) noticed the downdriver not long after I had posted things to The Database (excellent work that). msieve is doing a c92 on line 1318 atm. Best hopes for 128370, and thanks for all the work on aliqueit. I'll try building v1.07 maybe tomorrow.
 2009-04-13, 20:44 #51 frmky     Jul 2003 So Cal 23×11×23 Posts 107310 had a fun weekend. It gained the downdriver for a short while, then lost it to 2^2. It kept slowly decreasing in size, though, until a 3 snuck up on it. It's now being driven back up by 2*3.

Actually, someone else pointed it out first. When I went and looked, I PMed you because of the height it was at. 128 is equal to my own record.

We're going to have to work long and hard to beat Markus, though, right now he's got the all time record at 134 digits.

 2009-04-14, 16:52 #54 antiroach     Jun 2003 F416 Posts I wasnt sure where to post this, but here goes. I recently stumbled upon this sub-forum and would like to help. Are there any starting numbers in the 100k-200k range that arent currently being worked on now and that also dont require too much computational power to complete? If so where can I get this list and how would i go about reserving some to work on? Thanks!

They've all reached 100 digits apart from some holes that Frank's working on. Most of the open sequences have drivers, meaning they will increase in size unless they escape the drivers (rare). The best sequences are the ones in the "Recommended Sequences" thread, although 100436 has been taken. Don't expect them to terminate. Have a look at some of the links in the "useful links" thread to learn a bit more about aliquot sequences. You may also want to participate in the team sieves: these are from sequence 4788 which Frank has reserved for the forum.

You'll need aliqueit, gmp-ecm, yafu/msieve and ggnfs. Reserving a sequence is easy: just post in the reservations thread. Then get the previous work from Frank's page (from "useful links"), get the converters (I posted them in the "reservations" thread) and convert the file. Adjust the settings in aliqueit.ini for your system and rename your "xxxxxx.elf" file (the converted sequence file) to "alq_xxxxxx.elf". Then put it in your aliqueit folder and run "aliqueit xxxxxx" where xxxxxx is your sequence. Aliqueit will take care of the rest.

WARNING: For the msieve path in aliqueit.inni, change it from "msieve" to "whatever your msieve filepath is". This allows you to use msieve for poly selection.
