I've inserted a statistics for sequences in the Wiki with own pages, depending on the type.

The recent days many Riesel prime pages were added, mostly from the beginning of the Riesel problem (first n-value > 8192), more to come.
All data inserted into the Wiki from my old pages are deleted there, to keep it easier what has to be transferred to the Wiki and to avoid outdated information.

A table for k*10^n-1 is created with some pages done for Near Repdigit numbers.

Also links in the sidebar for Woodall/Cullen were added.

The prime for 6*354^n-1 is 6*354^25565-1, not 6*354^25561-1, see https://mersenneforum.org/showthread...12993&page=195

Done

Also, for the page https://www.rieselprime.de/ziki/Prot..._bases_least_n, I think this table can show the test limits for the generalized Fermat numbers without known primes, just like the test limits for other forms without known primes, e.g. 4*32^n+1 at n=1717986917, 4*53^n+1 at n=1610000, 4*155^n+1 at n=1240000, etc., since these forms may have primes, like the forms shown "0" in the table.

The test limits for the generalized Fermat numbers without known primes are:

2*512^n+1 at n=2001599834386886
4*32^n+1 at n=1717986917
4*512^n+1 at n=62549994824589
4*1024^n+1 at n=858993458
10*1000^n+1 at n=1431655764
12*12^n+1 at n=16777214

and they also should be in the "Wanted values".

Note: 8*128^n+1 has no possible prime, thus still should show "-" like other forms with no possible prime.

For Williams prime PP 327, (327+1)*327^135981+1 is prime.

Also, Williams prime MP 342 is checked to 200K with no prime found.

Done

Also, for Williams MM least and Williams MP least, CRUS has started R478 and S817, but both only tested to 2.5K

No, 477*478^n-1 was tested to n=200k by Steven Harvey and 816*817^n+1 tested to n=100k by me.

@Kar_bon, you did not do posts 202, 203, and 204 (you only did posts 205, 206, and 207) in pages https://www.rieselprime.de/ziki/Prot..._bases_least_n and https://www.rieselprime.de/ziki/Ries..._bases_least_n

No, this should be done in the k-value pages or the CRUS pages if available so that page for smallest n-values could take those n-values from there automatically.
I'm currently working on other topics and I think Gary is not willing to keep CRUS pages current in the Wiki, so no: I'm not willing to create those pages for every base of my own.
Same procedure should be done for all Williams primes pages, but no time to do so yet.
