Factoring database - Page 18

schickel · 2009-04-05, 08:00

Just out of curiosity, what are the current stats on the DB: size, prime count, etc....?

The numbers are still going up - about 15 extra numbers per second.

Shortly after the invention of "very high limits", someone put M1061 in the queue. Now the C254 from M961 is in the queue.

Edit: It isn't any more!

Edit2: The rate of numbers being put in to the primality queue is fluctuating wildly - at one point it was about 100 per second.

Edit3: There is a C83 being sieved. On the worker status page, it is given as "Working on <number> since <time sieving so far>. Could you replace "since" with "for"? That is not what "since" means.

I just reported the .elf file of aliquot sequence 184578, which 10metreh has posted, to the database and noticed the following:

Line 1714 contains 7069^2 as a factor. All lines which follow this line have not been shown, because on importing the .elf file, the database took the squared 4-digit prime as an unfactored composite. Anyway, clicking "TF to 1e6" in such a case does the trick (once you see the small unfactored composite.)

Sorry. This was neither intended as an offence, nor as an offense. This was just a typo.

P.S.: smh was faster by a few seconds when I intended to correct it.

The whole "offence" thing was a joke.

I've deleted the original post.

I have two requests that hopefully should be easy.
Could we have a mod function with the % sign?
Could we have a way of using the previous iteration as a variable in a formula?

I have a question. Does the database query itself when doing p+1 and p-1 testing? That is, if there's a hard composite 1 away from a number to be factored, but it's already been factored in the database, is that used?

Scripting issue:
I want to query the database to get all factors of completely factored Mersenne's.
Is there an easy way to get a flat output of let's say M823?
http://factorization.ath.cx/search.php?query=M823
I'd rather not have to work through the HTML stuff; it would be nice if all digits of factors were visible.
Perhaps someone already has scripting I can use? Or: Syd, could you make a switch like "?outputtype=flat" or something?

J.F. · 2009-04-18, 18:28

Nevermind, I think I can work-around the problem with the format I just found on

Are you are that Will Edgington already provides this service in the file factoredM.txt?
