second problem:

The program output tells you it cannot find the sievers. While I agree that is a problem, you didn't tell us whether the siever exe's are there in your folder (meaning a path error of some sort), or that you don't have / don't know where to get the lasieve executables.

I haven't done any factoring on windows in many years, so I can't direct you to the siever executables- sorry. Someone surely will soon in this thread!

[URL="http://download.mersenne.ca/GGNFS"]Here[/URL] are some. Thanks, James! :smile:

I do have that, i found a sourceforge link in msieve. The problem is on yafu's end. It uses a default link for gnfs-lasieve4I12e.exe. does anyone know how to fix that?

Read the docfile.txt in the yafu.zip and the parameter "ggnfs_dir".

[QUOTE=garambois;603176]There must be an error : 17^123 is not terminated on FactorDB.[/QUOTE]

I'll get back to 17^123. I am unsure how I erred.

76^66 is kruoli's reservation now.

I have expanded my scripts to cover all the existing tables below a base of 2^32. The scripts are supposed to skip any sequences flagged as reserved in the tables. I will try to also keep track of any more recent reservations that haven't made it into the tables yet. If I fail on either of these, please post here, noting my failure.

Since I'm now generating the lists via script, rather than manually adding new sequences I've brought below 140 digits, I will "probably not" post additions as I have in the past.

reserving 54^96 until it goes up or terminates
Terminates after 60 terms (prime)

reserving 101^53 until it goes up or terminates
93^65 is also unreserved

101^53 Terminates after 74 terms (prime)

93^65 terminates in P21
52^94 terminates in P17
439^55 terminates in P7
