Finished GFN divisor range n=22001-25000, k=2M-3M


No GFN divisor found :(


I attached all PRPs I found, maybe someone run a short divisor double check on them with pfgw64 -gxo


EDIT: should have posted in gfn results

No GFN divisor found :(

I attached all PRPs I found, maybe someone run a short divisor double check on them with pfgw64 -gxo
I tested your list of PRPs (184211 unique numbers) and verified that none of them is a GFN divisor. This was a bit surprising since my estimate for this particular range was 2.5 GFN factors. Looks like you were just unlucky this time. I hope you have better luck with your next range!

BTW, I noticed that there were 8 duplicate PRPs in your list:

2059589*2^22485+1
2059719*2^22485+1
2215627*2^22250+1
2219569*2^22250+1
2306235*2^22713+1
2555325*2^23235+1
2860173*2^22950+1
2904049*2^22782+1

Apparently whichever sieve program you are using can generate duplicates.

I have completed



FermatFactor=221,230,250000000000000,300000000000000


No factor found, result file is attached.

I used mtsieve for sieving. Could this be due to pfgw not updating the .ini file every tested number? So when I stop the running processes and restart, pfgw restarts somewhere before the last tested numbers and some numbers are tested twice, thus leading to a few duplicates.

To reduce I/O on the .ini file pfgw will not write to it after every test. IIRC it writes at most once per second. These tests take less than a second.
