Done. 2289 PRPs found, but no Fermat or GFN divisors.

I don't know, but I would think that 281e12 adn 350e12 should work.

 2016-12-09, 14:33 #28 wombatman I moo ablest echo power!     May 2013 1,741 Posts It's running fine, and based on the ETA to complete the current step (~1 day), I think the 15 days is a good estimate.

Would you please PM me your real name and nationality, so that I can update the Fermatsearch database?

Thank you Mark, I will add the ranges to our wanted list.
BTW, I am not sure about ranges with N > 100,000, as some of them had already been run on another distributed project.

I guess you did a search for gfn factoring as well, because the following ranges had already been done:

6150-6999 400,000 800,000 done by Gary Gostin (no gfn)
10,000-11,000 50,000,000 100,000,000 done by Gary Gostin (no gfn)

 2017-07-07, 16:51 #32 rogue     "Mark" Apr 2003 Between here and the 22×7×223 Posts I'll look into that. In your table you have a number of rows where "to n" < "from n". What does that mean? I would expect "to n" to always be larger than "from n".

That was my mistake on the first range. I intended to copy the "number of days" from a previous post and ended up copying the whole line. As for the second range, I didn't see it on your webpage unless it was submitted after I grabbed the data earlier today.

Here is the raw data. You can ignore n > 100,000, but if you know of a specific project that did the work and did the GFN testing, then I can see if they have data available to fill in those gaps.

Code:
6151-6199     900000000 2500000000
6201-6299     800000000 900000000
10003-10999   50000000 269000000
14501-14999   30000000 70000000
80001-80999   90000 100000
114000-119999 40000 99999
120001-129999 30000 40000
130001-139999 20000 30000
160001-169999 15000 20000
181744-189999 13000 30000
