Riesel primes for k<300
This thread is only for Riesel primes k*2^n1 for k<300.
The old pages of my RPPDb (Riesel and Proth Prime Database) are outdated (last edit Dec. 2018) and I will not update there anymore. The new data inlcuding all available history of this forum (or others if needed) will be collected and shown in the Wiki. At first sight the k=43 page shows some history entries from 2007 to 2018 (with still a hole) including  current primes found so far with available Top5000 IDs as link  data of the last history entry (will be used in the table, see below)  history links to the specific post (if available)  reservations or only notes The data table for all k<300 can be found here and is generated automatically from all the kvalue pages like above. Technically:  The base template is the Riesel prime, which does the most things like categorizing, display comments and layout automatically.  The history can be filled in with some small templates like HistC (others: HistF/P/R/S)  To reserve a kvalue the parameter "RReserved" has to be filled with the name/project.  If a value is reserved, it can be shown on the Personpage as well (example here)  Post links to other sites are possible like FreeDC, PrimeGrid, NFS@Home, Yahoo  So called "Multi Reservations" (a range or a list of kvalues) reserved by a project can be done easily without editing every kvalue again (Example: RPS Drive 10, kvalue 10781) Advantages:  Old page only showed the last edit, the Wiki can contain the whole history  Every registered Wiki user can update their own data: no need to wait until done by admins  The summary table is uptodate after kvalue edit: minimize double reservations Note: The Wiki is not a replacement for this forum: reservations/ranges done/primes found should still be done in the designated threads. Suggestions welcome:  Leave the "Reserved" history entry or delete after range completion? Sometimes reservations are done but not released.

I would leave the reservation as part of the history if it is actively being worked on or if it was completed (perhaps with a note stating it was completed). If no work has been reported for a while (say, 6 months) and no contact has been made with the person who made the reservation then delete it.

I've updated the first kvalues with all history entries (see post #2) from only one thread.
Findings of primes will be added later, first try to get a current work version of all k<300. There are many reservations ongoing without any results in 5 or 7 years, please check all your reservations. Last fiddled with by kar_bon on 20200310 at 16:35 Reason: res

Current work done:
All Riesel prime k<300 are now with information of ~3000 posts of this forum and all available IDs and dates from the Top5000 list. More information see post#2. I've also included more persons, where you can see (if available) current reservations. Last fiddled with by kar_bon on 20200411 at 17:51 Reason: persons

The given nrange for k=5 is from the reservation of VBCurtis which seems not yet completed (see first post of 5kthread).
I've also not yet included the whole thread for history data so that reservation could be listed then to make it clear. Only the highest continuous completed range from n=1 will be given in the Wiki.

That might take me a little searching to find results from that reservation....
I'll find it, or rerun the range. Shouldn't take more than a week or two.
