Paul, that is indeed good news. Although 3+2_458 and 5+3_286 stood no chance ofcourse against the running ECMnet 2.7.3 client loaded with GMPECM 6.1.2. I saw that we moved on to the B1=1000000 range which hopefully will find large factors of the remaining composites.

Does someone want to get me up to speed. I can't see a simple summary in this thread, and it looks like people are looking outide the range listed in :
http://www.leyland.vispa.com/numth/f.../anbn/main.htm What ranges are of interest in 4^n+3^n? For example, if you're going beyond 350, then n=351 has this: (and this was completely trivial, ten minutes work on an old P3) Code:
? C=subst(polcyclo(702),x,3/4)*4^eulerphi(702) 11918373797533701570043364702426895921596861568814732254151942914041772942209494877872906695265479347288410269727764182956919754721 ? C==(314642719 * 3487347163 * 25876141241263871115871 * 6176913048463443825557539 * 496737950461620637069 * 136806203355749662909017142119554851933674613) 1 I'm interested in the ranges for pretty much all of the tables (it's too hard to describe the ones I'm not interested in).

While others are free to disagree, I like to follow that old saying from everyone's mom: "finish what you started before moving on to something else". Let's finish the composites in the current tables before extending them further. Of course some(many) tables are finished to their current limits. Extending them would be fine. [IMHO]

It's fine by me if you all stick with the table sizes you currently have. While you're crunching and pondering, I shall just do a little playing with 4+3 on my own, just above the curent limit. I'll stop when my factorfu runs out, and mail the results to Paul. In fact, it's _BEST_ that you stick with your current table sizes, as that guarantees I won't tread on your feet, and you won't tread on mine! Good luck, and happy cracking!

Does anyone have a list of which tables are complete, as it definitely makes sense for me to tackle those first? I can check each of them visually, of course, but it's a little silly wasting rediscovering what must be known already by someone else. Cheers.
