Hi, why can't I find the tables for the "extended Sierpinski problem" and the "extended Riesel problem"? Also the tables for all kinds for Williams problems... (all of these tables are created by me, where are the tables now...)

All of those tables where much too long.
For example there was a table for Williams primes with 8 different kinds of numbers in one table.  unreadable  editing is a horror (finding the right entries)  (almost) no test limits given Having in mind that every edit of such page (only one character is enough) will save the whole page again in the database and you edited such pages more than once (example: 20180402 from 05:07 to 05:45 30 times! in 40 mins) is not acceptable anymore. Your biggest page (Pseudoprimes of 5 different forms in one table with colors) was 3MB in size, the biggest page I've ever seen in a Wiki! Every edit will save 3MB of text in the database! The SQL dump of the whole Wiki is only 16MB in text format! At least that page could not be edited because the browser/wiki software was unable to handle this. Big data collections are not allowed as pure wiki pages, but only in file format like attachments as given on the example page or at the Cunningham project page. I've not yet tried it for those overloaded pages because I have to evaluate first how this can be handled and find the best to keep the database fine and to keep it simple for users to edit in an easy way. So templates have to be generated first like for the Riesel or PDF with acceptable and reliable data for storing.has to be generated. You were blocked on OEIS and Wikipedia because of those big tables in mass with not verifyable data and restoring your deleted edits in several times. I will not allow such behavior in this wiki and if I got time to include those pages again (in a different way) you will see them.

We always wondered why the wiki database was over 500 megabytes!

The dual of Proth prime k*2^n+1 is 2^n+k, for odd k. (there is no prime for k=78557 with both forms) The dual of Riesel prime k*2^n1 is 2^nk, for odd k. (there is no prime for k=509203 with both forms) Last fiddled with by sweety439 on 20190403 at 02:02

Thanks for the link.
The naming of special numbers is surely an issue and I try to explain these in the Wiki. I know using "Riesel prime" for primes of the form "k*b^n1" is not the best way but it's used over years not only in this forum. C.Caldwell is also using only a few named numbers in official. On the other hand it's easier to name a wikipage "Williams prime" instead of "(b1)*b^n1", also the search/find handling makes it more readable. The PrimeWiki is still in contruction mode instead of real professional use but if you got any suggestions to handle those namings different/better, I appreciate you motivation.

https://oeis.org/wiki/User:Charles_R...special_primes but I would hesitate to suggest my names as as 'official', though I've tried to stick to the straight and narrow. (Also I think only a fraction of these would be of interest to you.)

Besides, will you add the page "Gen. repunit prime" (primes of the form (b^n1)/(b1) and (b^n+1)/(b+1))? and also the pages "Gen. repunit prime least", "Gen. repunit prime without" and "Gen. repunit prime table"? See my page https://docs.google.com/document/d/1...iu7IzXAZGo/pub, I know that this is PRP searching, not prime searching.
Done. Last fiddled with by kar_bon on 20211024 at 08:00
