Generalized Cullens/Woodalls

[rogue]

In an e-mail with Steven Harvey, he has not been maintaining https://harvey563.tripod.com due to health reasons. He would be happy if someone could take it over.

I have also tried to contact Gunther Low, who was coordinating the list of Generalized Cullens for b <= 100 at http://www.loeh.name/guenter/gc/. His page hasn't been updated in over 3 years and he has not responded to any e-mails yet. This list for 100 < b <= 10000 is on Steven Harvey's site.

It would make sense to me if these projects were over to the Prime-Wiki at https://www.rieselprime.de/ziki/Main_Page. Is anyone interested in setting that up and moving the data over? Once that is done we can start some new threads here to manage reservations.

Thoughts?

They are there:
(Gen.) Woodall and (Gen.) Cullen.
For Cullen there's also a link to an Wayback page from Daniel Hermle.
Automated tables and templates to fill in more data are also available.

That is good to see, but these tables are missing a lot of bases. Who wants to take a crack at updating them? Maybe this will need to be done in chunks over many days by multiple people.

Base 11 for both GC and GW has only two primes in the range 500 to 100K:
1184·11¹¹⁸⁴-1
1308·11¹³⁰⁸-1

This base seems already tested to n=500k, check S.Harveys page first.

Good to know, thanks! In that case, I am going to sieve from 500K onward.

BTW, I do not have a login at rieselprime.de, so I cannot make any updates to it. I have requested one, but no response yet.

The source data has inconsistent formatting. Otherwise, I'd suggest writing a parser and having a bot account (which I have on the Prime-Wiki) do most of the grunt work uploading everything.

I would not create for every base of Woodall/Cullen type listed at S.Harveys source an own page in the Wiki.
Say for all bases<100 and for all bases where a prime exists in the Top5000.
The remaining should be listed as a table uploaded with a CSV-file, there're 10k bases with mostly tested to n=10k but no known prime found, tremendous waste of space otherwise.

Maybe it could be split into multiple pages with 1000 per page or a link to a text file which is basically a copy of his results.

I have the ability to edit now, but it would be a significant effort to create all of the pages necessary. Since I am not a guru with the Prime-Wiki, maybe someone else knows of an easy way to have this data available on it.
