Since I haven't provided an update for quite some time (if ever) for these particular numbers and there are no data shown:

216840: size 119, i4926, 2 * 3² * 7 * 2557 * 2587163 * c107
- This number is still shown in the "Released Sequences" thread, which may not matter, since it is also shown as reserved by me in the "Aliquot sequence reservations" thread. I might release it soon, anyway, since it really hasn't been that interesting. It has simply kept up a slow to moderate climbing pace, mostly (all, but once, I think) taking between 10 to 20 iterations per digit.

257184: size 120, i1643, 2² * c119
- This one has been at least a little more interesting, with a few downswings. It's currently on a run of powers of 2, drifting up and down slightly. I'll probably keep it until it reaches 125 digits. Right now it's in hour 26 of ECM on the c119.

Several big NFS jobs coming up:

Code:

06/10/10
  Seq   Index  Size  Co-factor   Driver/Guide
171018   2233   137    136       2^5 * 3
363270   1699   151    137       2^5 * 3
604560   2594   137    135       2^2

All three survived preliminary ECM testing... Hopefully the guide on 171018 might change.

In post 537 of this thread, unconnected reported that it was at line 5945 with 125 digits. He hadn't reserved it. Before that, fivemack reported (post 425 of Subproject #3) that a mystery worker had worked on it. Oddly, it is only at 97 digits in the DB. Please don't work on it. I'll check it out.

740856 is broken in the database at line 5692

Line 5693 should be 1052741490055231522388450724579128838383603351221563896015509204671258174191004784

If you put that into the db, you get up to the 125-digit number reported by unconnected, at iteration 252 = 5944 of 740856.

firejuggler · 2010-07-15, 18:27

line 5692 contain a 155 wich is considered as composite even with the 5*31 factorisation, wich make the line 5693 false and mess with the DB

Ah. It is very irritating when people work on false sequences created by DB errors causing people to think there isn't an error.

Syd hasn't been active since 9th of June (sic!), errors in the DB seem to accumulate....

I think it's time to save the sequences to .elf file (if someone has time and ressources to do so)...

It's been a while since my last update:

Code:

07/29/10
  Seq   Index  Size  Co-factor   Driver/Guide
363270   1718   158    150       2^9 * 3 * 13
604560   2617   143    110       2^3 * 3^6

Since I am actually making progress, I may be able to keep 363270 until at least 160 digits.
