The next days i will create several threads for some described categories where results can be posted.

[kar_bon]

i've inserted a new data-page for Constant-n Searches.

see the 'Data Section' menu. more to come.

[kar_bon]

i made a greater update of all pages (changed html-code: 'class' instead of 'id', no visible change of the pages, only html-restrictions) so all will be shown updated, but without any new data on most of them.

new:
- page with download(s): all shown prime in the DataSection in a ZIP-file in LLR-input-format (one k/n-pair per line ascending in n)

the ToDo-list grows but i keep the data current (new primes from Top5000 added)!

i'll include more low primes 10k<n<20k for 3000<k<10000 from T.Ritschel (thanks)

Update of the Statistics-page (without Sophie-Germain yet) and a new Download (all Twins).

[kar_bon]

It's time for a resume for 2009:

I've updated the statistics-page (Sophie-Germain not yet):

currently in the Database:

- 7900 k-values
- 150000 primes
- 3100 twins
- added all Aliquot Sequences < 1000000: currently 9345 open ended
- added pages for Home Primes Base 2, 6 and 10

So for 2009 i've added about 350 k-values, 14000 primes, 70 twins and 3700 Top5000-links
(to consider: all k-values < 10000 and all twins < 10000 were already in the Database!).

Historical note:

My first page from April 2007 contained about 1500 k-values with 12000 primes!

Although i've added such an amout of data the last 3 years, there's much more data to fill in and to update.

As my real life will allow me, i'll try to spend much time on updating almost every day although it's not visible at all.

I thank everybody contributing their results here/me for including in the Database.
Information is what i need: i'm aware of new primes in the Top5000 Database from C.Caldwell but 'small' primes everybody should send them to me.
And of course it's important for me to know the ranges done.

Lookout for 2010:

- Updating all Project pages
- including more primes from Top5000 (older/smaller ones)
- extending the Constant-n-Search page and the Payam-page
- finding some errors (i'm sure there're some)
and
- finding much primes myself (44 Top5000 in 2009 and many small ones)

7915 k-values
153084 primes
3125 twins
8460 Top5000-links

I've updated all k-values from the Riesel-Problem with current search limits from PrimeGrid.

There're 64 k-values. Two of them (342847 and 444637) are done to n=5.0M, because of their very low Nash-weights.

I've updated the Download-page with entries for LLRnet V0.72 and V0.73 and the history of this tool.

[kar_bon]

8050 k-values (135+)
161669 primes (~8600+)
3456 twins (~330+)
9224 Top5000-links (~760+)

[kar_bon]

Graph of all primes of the form k*2^n-1 with 1 <= k <= 10000 and 1 <= n <= 3,000,000 in the Database as of 2010-07-11: 123,139 counting.

18 primes with n>3,000,000 are not shown here.

[kar_bon]

I've finished the RPS 9 k's drive page. This drive was done in 2009 for 9'ks < 300.

I've also updated the k<300 page but not yet for the 6th drive and k=5, 15, 17, 105. Those pages will be the next goal for updates.
