I've changed/updated the page in the PrimeWiki for least Riesel values.

Now the wanted values are stored in a data file (no adds of the page in the database, only file system) with a direct link for the base to the CRUS data table.
Some values are not handled by CRUS, because the k-value > CK.
The table is sortable by base, max n-value or date to find some special cases.
If there's no link to a history in this forum I've set the date to today.

I've done 12*263^n-1 (not considered by CRUS) for a longer period and is now officially reserved by me.

The same will be done later for the Sierpinski table.

Can someone update this into the zip files in the OP please?
Besides,from https://primes.utm.edu/primes/page.php?id=132360, b = 650 Can be eliminated from the remaining bases for k=4.
Also, k8 b328 has been searched up to n=1m.

It looks like I haven't updated the first post here in months. I keep everything updated locally on my machine. I'll upload the files shortly.

Edit: First post updated.

I synced up the files in the first post here with the Wiki that Karsten has created. In doing so I also updated several bases on the Wiki. It will take a little while for the Wiki changes to take affect.

Wiki for small Proth primes, least n-values updated with 8*908^243439+1.
Top5000 gives "Anonymous" as finder, different from here, so inserted in the Wiki also.

I am attempting to keep the attachments to post 1 in this thread updated at all times instead of updating it once every few months. Please point out if anything is incorrect or out of date at any time and I will correct it as soon as I can.
