A bit of trivia: it had ridden 57 (!) downdrivers so far...

I updated the status of all the reserved seqeunces. Current downdriver count: 3.

Oh, and we had a sequence exceed 12k lines! :w00t:

I posted an updated status on everything [URL="ftp://ftp.frontiernet.net/pub/users/aliquot/AllSeq.zip"]here[/URL]. I expanded the length column by one to accomodate our outstanding sequence.....hopefully it will not remain alone too long.

seq 245274:i1344 no guide : 2^7*1993

this sequence is driving me crazy : it when by almost every driver/guide possible

Lucky sigma on 933436:i12320 c133:
Using B1=11000000, B2=35133391030, polynomial Dickson(12), sigma=536664592

The sequence reach 150 digits now :w00t:

Just playing around, I got this to happen with ECM work by the DB (from 356272):[code]1167 . c114 = 2^4 * 3^2 * 5 * 31^2
1168 . c114 = 2^5 * 3^2 * 5 * 31[/code]If it were only that easy all time :cry:

[QUOTE=fivemack;271946]May I reserve 890960 and (probably very briefly) 281592?

398856 is currently at iteration 1152 with 2^4[/QUOTE]Looks like you had quite a ride!

Unfortunately, 2^2 * 7 has taken over....

While the rest of you were having [URL="http://www.mersenneforum.org/showthread.php?p=273164#post273164"]fun[/URL], I just spent ~ a week factoring this (604560):[code] 2687 . c152 = 2^5 * 8535929 * p57 * p87[/code]to get this:[code] 2688 . c152 = 2^4 * 31[/code]Arrrrrrgggggggghhhhhhhh! :max:

I ran into some trouble with my 996666. Successfully pushed it few steps more, till T903, even overpassed a difficult C111 at T899 (and an easy C111 at T902), but now I really have trouble. I have run into a C108 that nfs (yafu) can't factor (?!?!?!?). After almost two days of sieving it is keeping telling me that he wants to extend the ECM limit or something like this (?!?!?) afer every few hours of crunching. NFS was selected automatically by yafu, no idea why (the limit in the ini file is higher, because I prefer siqs, at least for that I know how many relations it needs, so I have an idea how much time is left) when I used aliqueit12. I have shut it down and started manual SIQS on it. Already about 10k relations from 196k needed, the progress is quite slow at this digit score.

If aliqueit12 have selected nfs for this number but your path to the gnfs-lasieve files is wrong aliqueit extend the ecm limit till the end of time or the factor is found.
