[quote=kar_bon;176146]- 0 < n < 100000: all seqs < 10000 are included with current data from Factoring Database[/quote]

You can get the status of 10000-100000 [URL="http://www.lafn.org/~ax810/five.txt"]here[/URL]. Note that [code]12012 1710. 2 C97 sz 97[/code] is wrong: this was the old status of 10212, and 12012 was a typo that was never removed. Note also that 11280 has its old status from before when a typo was discovered in the earlier work.

Speaking of 10212 - I have picked up this one again and will do a few more iterations, but I don't plan to take it very far... (well... I might change my mind if it gets rid of that 2*3 driver.)

Thanks for updating the list!

I did notice for some of the 10000 - 100000 range were not in the database. For example, [URL="http://factorization.ath.cx/search.php?query=&se=1&aq=10344&action=last&fr=&to="]10344[/URL] only goes to 74 digits. Is this because someone else is doing the 10000 -100000 range? I was curious about what was the lowest sequence for which work done is NOT in the database, and 10344 appears to be the answer.

It actually goes to 78 - the size of the initial composite is not the size of the remaining composite.

Clifford Stern maintains the 10000-100000 range, and he is constantly pushing the sequences in it higher. However, he has not put all that work into the database.

now all seqs for 10000 < n < 100000 are shown on the Summary pages, too.

but: the listed depths are mostly not in the database, yet.

same for n>250000.

so, i think, for a first milestone, all open (and some ended) seqs for n < 300000 are shown on those 3 pages!

next steps:
- check data with database
- insert more seqs in database
- stats/odds page
- try to 'hire' Clavier, Stern, Zimmermann, Bosma, Creyaufmueller and other contributors for this forum/database to share their results

suggestions?

Not sure if this is useful, but it is a list of the numbers that reach 1 quadrillion(10^15) before the merge with an earlier sequence or terminate.

The list is of the form:
<number> | <maximum> | <merged or maxed>

The maximum is pretty low. I used 8 byte numbers with trial division up to 2^26 from a program I wrote before finding this group. However, since 1 quadrillion is less than the square of 2^26, all sequence reached 1 quadrillion. In fact they only stopped when going over 2^64, or some factor was greater than the max prime squared and no prime divided it.

I included this because it has the 3740 numbers that might be significant and includes ones that may have been weeded out because they merged at some point after 1 quadrillion. I don't know if you want to put these numbers into the list, or whether you already have this info, but I figured it wouldn't hurt to mention it.

Out of the 3740, 113 merged with a previous sequences given the limits above.

I also have a list of:

Those that reached 1 trillion, but not 1 quadrillion. (340 numbers)
Those that reached 1 billion, but not 1 trillion. (662 numbers)

Here is the numbers that reach 1 trillion but not 1 quadrillion.

and the one that reach 1 billion but not 1 trillion.

Help needed!
 
i'm trying to complete the page for 100k<n<200k sequences.
but there're a lot of them not yet filled with the whole seq in the database from Syd.

so, please, anyone can help here!

to do:
- go to the summary page [url=http://www.rieselprime.de/Others/Aliquot100.htm]here[/url]
- (by now all seqs upto 122k are filled in) click on a seq-number
- compare the given parameters from the summary page with the database

- if the database-index is smaller, do:
- download a seq-file from Franks page [url=http://www.frontiernet.net/~aliquot/alq/100k/]here[/url]
- convert the *.ALQ file into a textbased *.ELF file with [url=http://www.aliquot.de/archiv/alq.zip]ALQ2ELF.EXE[/url]
- upload from missing index to the database
- sometimes the database needs a TF to 10^7 to bring the composite cofactor like in the summary noted!

i will try to fill in more, but it's very timeconsuming (got all those elf) to upload them.

if a file is in the database, i need only seconds to verify against the summary page.

after all seqs are in the database and the summary is checked, i could include some stat there, too:

max/min/mean number of indices/sizes/composites so everyone can see the progress in this range!

Karsten, 157752 is reserved by D. Stevens (aka henryzz). You seem to have missed it out.

Mini-Geek 2009-07-04 12:20

Let's do some reservations to help make the work filling in the DB a bit more orderly:
Reserving 122540-130k (122540 is the first after Karsten's indicator on the page)
Now if anybody wants to help work on it while I'm still not up to 130k, you can just start at 130k. :smile:
Edit: Do we need to do anything when the DB has a newer status than your page? e.g. [URL="http://factorization.ath.cx/search.php?aq=123450"]123450[/URL]
