I posted an update to the generate_maxlen.py script which revamps the CLI interface. It now uses the Python argparse standard library module, which makes it a lot nicer. I've also added support for specifying a max [I]n[/I] in lieu of a max FFT length and moving the verbose flag to the CLI. It now has a built-in help message generated by the module, so check that for the details.

Perhaps an admin should make a new thread for such script-related posts, better finding later.

The (near-)Woodall [I]k[/I]'s listed in [url]https://www.mersenneforum.org/showpost.php?p=550539&postcount=363[/url] have been completed to [I]n[/I]=425k. The following primes were found:[list][*]1993191*2^405251-1[*]582833*2^417560-1[*]197673*2^421871-1[/list]

I've completed the remaining RPS 9th and 10th Drive [I]k[/I]'s with missing ranges from [I]n[/I]=325k to 350k. 14 primes were found, which are attached. I brought an old laptop into the fold, and I have a new Kubuntu Focus on the way, so this project (to [I]n[/I]=400k) may be done by this summer.

The following primes were found:[/QUOTE]What are (near-)Woodall k's? I know about near-Woodall primes where k is n-1, but that doesn't seem to be the case here.

(General) Near Woodalls are primes of type (n-1)*b^n-1 or (n+1)*b^n-1, examples [url='https://www.rieselprime.de/ziki/Gen_Woodall_prime_M_2_table']here[/url] or [url='https://www.rieselprime.de/ziki/Gen_Woodall_prime_P_2_table']here[/url].
Most of the are not spotted immediately, because the normal form in for example the Top5000 page is displayed different:
Example: 1060*2^1059-1 is normalized written as 265*2^1061-1

To be clear, these are [I]k[/I]'s where near-Woodall and Woodall primes were found for larger [I]n[/I] values, and I'm filling in the untested missing ranges. I'm not actually finding new primes of those forms, which are searched for largely by Steven Harvey and PrimeGrid, respectively.

Reserving k=3317

As of March 27, the (near-)Woodall [I]k[/I]'s listed in [url]https://www.mersenneforum.org/showpost.php?p=550539&postcount=363[/url] have been completed to [I]n[/I]=450k. The following primes were found:[list][*]1268979*2^426051-1[*]1195203*2^444882-1[*]197673*2^447700-1[/list]

[QUOTE=Happy5214;540140]I'll also tack on k=14549535 for 125k < n < 300k as a double-check.[/QUOTE]


Happy,

From a year ago...was this done? I'd like to go ahead and double-check k=14549535 for all n<=300K and then test it up to n=500K. Is that OK?

Funny you mention that. I had started work on that [I]k[/I] in late February, but I had suspended work on my local PRPNet servers for a bit in March to work on the GIMPS PRP-CF-DC backlog. I have since resumed work on both clients. That [I]k[/I] is currently at [I]n[/I]=288k, and I should get to [I]n[/I]=300k by the end of this week. You can take over from there.
