Please send me your created data from the Harvey-page for including in the Wiki. I detemine if it's doable then.

I haven't created anything at this time. I only have the .txt files from his page.

There is also the data from Gunther Loh's page, but he only has bases <= 100. Prime-wiki only has 20 of those bases.

It seems to me that the process to create a new page with all of the requisite data is time consuming.

I suppose that if someone created all a bunch of empty pages (which I assume is manual) that it would be easy to write code to generate the contents of those pages from the older projects.

Ok, then this to keep in mind:
Harvey's page as said got many bases only tested to n=10k or so but no prime found.
Like

Code:

12800 - 12999 [13001]
13000 - 13099 [13100]
13100 - 13199 [13200]

Why should I create 400 pages in the Wiki with all the same data only tested to n=13k by Harvey?, no date available, no primes, almost empty pages.

And:

- 512 1298(Walker),11223(Harvey) [222000] (from that page)

but b=512 has this n-values for primes: 2, 6, 25, 1298, 11223

or
- 2048 6950,34044(Harvey 10/3) [91000] reserved Harvey

but b=2048 is also prime for n=9 and n=26 and is the reservation active, seems not

So, the data base is not correct and fully tested and I can't trust it at all.

Another thing:
Look at base=4: there're all 'normalized' forms for Riesel type of those values included as note. Who will do this?

As mentioned before:
- add only bases b<=100 with own page
- add bases b>100 with own page where an entry can be found in the Top5000
- remaining bases listed as table/CSV data
The whole work will last for weeks to retest some data and collect links.

The same for Cullen and others.

If you want to help here: test for (all) bases the small n-values if there're more missing entries.

I would be okay if you combined ranges of bases without a prime.

This page, https://harvey563.tripod.com/GWlist.txt, is easier to read (and parse) than https://harvey563.tripod.com/General...dallPrimes.txt. I assume it is up to date.

You can ignore any reservations from his pages. They are ancient. Old reservations (> 3 years) on the Prime-Wiki can be removed. I think that managing reservations via a sticky thread in merseneeforum should be sufficient for most people. Maybe Prime-Wiki can just point to that thread for those who want to make a reservation.

I do not know if any other bases need primes to be normalized. It shouldn't be difficult to figure that out because as b increases there will be fewer normalized primes. IMO the only primes that need to be normalized are those found t tk5.org. I suspect that those are already captured on Prime-Wiki. Anything else won't need notes and if we don't have history for when a prime was found, I am okay with that.

I am okay if you want to put the bases > 100 into csv or txt format (like the current pages). Note that the Carol/Kynea page has hundreds of bases. Maybe b <= 1000 is better.

It appears that you have some ideas how to tackle this. If you anything concrete that I can assist with, just let me know.

As for the data not being accurate, that is the risk of being on a wiki where multiple people can update. It won't be perfect, but those who are diligent will work to correct mistakes.

I have updated the GW list.
Over 2300 with at least 10.000 digits.
The additions are without name and date..it was to elaborate to fix it.

That link produces an HTTP 404 error for me.

Traditionally, it is asserted that n+2 must be greater than b, which Prime-Wiki ignores. This is mentioned on https://www.rieselprime.de/ziki/Woodall_prime.

This is correct, I rewrote all tablenames for a better systematic .
Now it is for this:

It will be hard to add to this until the reservation system is moved. Both the Generalized Cullen and Generalized Woodall lists leave lots of opportunities for new primes that shouldn't be too difficult to find.

Are there public sieve files for any of the gcw bases?

Which software is most efficient in sieving gcw?

Not that I am aware of.

gcwsieve/gcwsievecl are the most efficient.

I'm hoping that kar_bon (or someone else) can create stub pages easily (maybe automated). Once that is done I wouldn't mind spending the time filling in what I can.

kar_bon · 2023-03-28, 13:07

Currently I'm inserting more Woodall bases into the Wiki, all b<50 are online now and some others.
If someone wants to reserve a special base, no problem: I can create it and the reservation can be filled in then (like for b=2).
No further work for Cullen so far but should work the same for any base chosen.
