[QUOTE=Jeff Gilchrist;285337]Although I think I found a small bug, if you ask for max digits 80, it still hands out C81 instead of returning nothing.

Look at: [URL]http://factorization.ath.cx/listtype.php?t=3&mindig=70&maxdig=80&perpage=20&start=0[/URL][/QUOTE]
Why do you expect the database to recognize a "maxdig" parameter?

@Jeff, the maxdig parameter is ignored with that query. It is only used with the "getrandom" style queries which return ids for composites in a specific range.

Yes, someone posted a script that had the parameter in it, so I incorrectly assumed that it would work. If it is not supposed to work in that context, then there is no bug after all.

Jeff.

Yikes!!

Someone has dumped a bunch of numbers near google in the composite queue. I'll add a worker (and maybe a second a little later).

RichD 2012-01-22 22:27

They're going pretty fast. Must be more than just my worker running.

I'll drop out once it gets into the C80s.

lost links?
 
I've recently noticed many n^n+(n+1)^(n+1) numbers have been removed (unknown) in the database. When I inquire they are added with small factors with the indicator "red asterisk". I have checked up to n=400. I also added the known factors to n=60. When inquiring the origin of the factor it states "Before November 4, 2018, 12:20 am". I have a table where I can add the known factors up to n=80K but that would be tedious.

Additionally, I recently added all the OPN numbers from the checkfacts.txt file (2.5GB) from [url=http://www.lirmm.fr/~ochem/opn/]this page[/url] over the past two years. I now question how many really "stuck".

Looks like factordb has been wiped clean?! No numbers of the form 2^n-1 or 2^n+1. :xyzzy:

Also n^32+1 ....

Someone is adding thousands of numbers of the forms k*I20000+1 and k*I20000-1. There are almost 8000 of them in the Unknown list.
