Default 3LM Table discussion

Phew!
There's a full update to the 3LM extension tables. (See post #2-4, merged.)
Also, added a live link to the 'massaged' FactorDB (which is still unaware of 3LM Aurifeuillian factors; had to punch them in).

Notice that it provides some nice entry level jobs for anyone.
For example: 3,1275M is difficulty only 162 (with a quartic, though).

PM me for poly, if needed. In short, it is
c4: 1
c3: 3
c2: -6
c1: -18
c0: -9
with Y1 = 3^42 and Y0 = -(3^85+1), ok? Will provide help with lims. Just ask.

Several easiest numbers are accessible to anyone armed even with a PentiumIII.

I might run 3,1275M. I'm PMing Batalov for details.

I wish that you had not done this. Now, people will want to pick the
low hanging fruit from the extensions, rather than work on other,
unfinished tables.

Ah, but you're assuming that if someone wasn't working on this, they would be working on unfinished tables. Well, I for one wouldn't. They're just too big for my small resources.

To completion? Certainly. But NFS@Home can always use contributors.

For mine too - the c153 from 2,1766M, which I did, barely fitted into my ressources. With my ressources I *can* pick some low-hanging fruit from the extended table, but on the unfinished (non-extended) tables I don't see a fruit hanging low enough to fit into my resources (especially RAM for postprocessing).

OK, I'm puzzled about this post (and the follow-ups). We're in a
sub-thread of the Cunningham Tables, on the 3+ list. There's nothing
on Sam's page about an extention/update to the 3LM tables. If the
update in question is an update to FactorDB, then please move these
posts to somewhere appropriate for FactorDB tables.

There's no shortage of entry level factoring projects. Let me
rephrase that; there's _FAR_ from a shortage of ...

(and a PS: was that an endorsement of NFS@Home in that post
of Bob's? I'd encourage anyone interested in factoring Cunningham
numbers, especially ones with increasing snfs difficulties; to have
a look at the "Status of Numbers" link on NFS@Home --- the
prospective November completions are on track to pass the October
rate; bunches of most Wanted numbers from the page 112 list
(still not yet online).

and a PPS: the bdodson contribution over there is primarily from cpu's
that weren't in the x86-64 condor pools being used for C/D, W+D,
B+D numbers, and the most recent W+mersenneforum+D number;
to the contrary, NFS@Home added a nice chunk of sieving for M941
off the books of the boinc effort.)

Let me also note that there are quite a few Fibonacci/Lucas numbers
available via SNFS for people with limited respources. See Blair
Kelly's web pages. SNFS Quintics will work quite well for these.

???

http://homes.cerias.purdue.edu/~ssw/cun/3LM

Doesn't that qualify as "Sam's page"?
