Edit: Nevermind. :smile:

I'll take the first two 19ers next in the t600 file. Namely...

7215061951^19-1
14702780467^19-1

I'm running a t40 on the entire t2100.txt file. As you might imagine, it's moving somewhat slowly, but I have gotten 2 hits so far. Both are listed below:

[CODE]73802780172859282526116255621169276883646159966413123442560015634653799890363179438487451848036117488820521055886954004260307189996609 = 3008821578312230732251914616889344993079941 * P92

I don't know if you can filter it but if the composite also appears in t800.txt AND it is < C183, those already have a t50-plus run on them.

Thanks for the heads-up. I'll grab the t800 file and check them against each other.

Quick check using [CODE]grep -F -x -f t800.txt t2100.txt[/CODE] and [CODE]awk 'NR==FNR{arr[$0];next} $0 in arr' t800.txt t2100.txt[/CODE] gives some common lines (thanks StackOverflow!).


Edit: Do you know the status of the other t-files (e.g. t1000, t1200, and t1600)? I'd like to remove any from them that have been tested higher as well.

No, that's all I know. It all goes back to [URL=http://www.mersenneforum.org/showpost.php?p=448503&postcount=445]this post[/URL].

I believe if a number appears in a lower numbered t-file it will also appear in all consequent higher t-files.

Additionally, it would be nice if you report your work so any future ECMers/NFSers would know the status of the previous work performed.

Absolutely. For now my work consists of running a t40 on the t2100.txt file (without the numbers from the t800 file that have been tested higher). Any hits I get will be reported here. :smile:

Actually, you can just report factors directly to FDB. Pascal (or someone) seems to remove them within a day.

I was referring to the no-finds, so re-work is not duplicated later on.

Got it. Given that I'm moving through them somewhat quickly, perhaps I can post a "checkpoint" of where I'm at or something every so often.

I'll start working the P47^5-1 numbers from [URL=http://www.mersenneforum.org/showpost.php?p=450998&postcount=484]post #484[/URL].

Taking these (GNFS) numbers next from the t600 file.

567661^37-1
8737481256739^17-1
33991...49^3-1
285996443195311^17-1
75882...57^3-1
