I've included k=13236795 into the Wiki with the history data from this thread and reserved for you.
Not listed the sieve depth, but could do if needed. Also I have to check the old 15kthreads for older information. And give me a clue: Here and in the Top5000 pages you are listed as "Valerie", but signing here as Cedric. I've inserted a Person page (including the current reservation) for "Valerie" (because official), if this should be changed please PM me.

Some bad news...
I have completed a doublecheck up to n=1M on this k. I found 7 missing primes. They are: 13236795*2^2331521 13236795*2^2402361 13236795*2^2588931 13236795*2^2597471 13236795*2^2660931 13236795*2^2673131 13236795*2^3145631 Valerie, It appears that some sieving was done incorrectly for the range of n=220K450K. I looked at the statuses in the old 15k search thread and found that your number of tests was much less than were in a file sieved by me to P=50T. Here is the thread: https://www.mersenneforum.org/showthread.php?t=3705 Here is a comparison of your number of tests in that thread compared to the number of tests in a file sieved to P=50T: post #11; n=220K231K; 744 tests; sieve 1439 tests; 51.7% tested post #20; n=231K240K; 576 tests; sieve 1183 tests; 48.7% tested post #21; n=240K250K; 674 tests; sieve 1319 tests; 51.1% tested post #22; n=250K280K; 1997 tests; sieve 3944 tests; 50.6% tested post #23; n=280K300K; 1295 tests; sieve 2652 tests; 48.8% tested Summary total for n=220K300K: 5286 tests; sieve 10537 tests; 50.2% tested; 5251 tests missing Your sieve depth back then was far less than P=50T so you should have more than 100% tested of my file. Clearly this only covers part of the "problem" 220K450K range but the above was all that I found with enough detail on your number of tests to make a comparison to my file. I suspect that post #6 was the error. Where you state "Currently resieving the range 220000 through 500000 with Proth 0.42...found 3000+ factors which NewPGen initially not found". You may have been sieving for Proth primes, i.e. +1 instead of Riesel 1, and the program removed a lot of good Riesel tests. Also 3000+ factors after you have already sieved for quite awhile with NewPGen seems like a large number. I suspect that was in error. It appears that you later used a different sieve for n=450K1M so the range of n=450K500K looks OK. I also looked at your results for n=1M to 1.3M. The number of tests keeps rising abnormally as the testing gets higher: n=1.0M1.1M 12752 tests n=1.1M1.2M 13218 tests n=1.2M1.3M 14251 tests n=1.2M1.3M has 11.8% more tests than n=1.0M1.1M, which is an unusual fluctuation considering it is a higher nvalue. You may want to look into that. For comparison a sieve to P=50T has 13293, 13210, and 13139 tests respectively for the ranges. I will continue doublechecking this k up to your current test limit of n=1.3M. It should be done in ~5 days. I've attached the primes and residues for n=01M and the sieve file for n=02M that is sieved to P=50T. The good news is that this k now has 113 primes for n<=1.3M...a very large number. :) Gary

Thank you gd barnes for double checking!
So it is time for an update... Since the confinements in belgium last / this year I cannot dedicate full time to this project I am staying with my elderly parents to take care for them I will see what I will decide when my last sieving range is done I hope that I soon can return home and finish this range Fyi I’am using srsieve 1.54 on my intel mac 2015 model Kind regards Valerie

k=13236795 doublecheck is complete to n=1.3M. No problems were found for n=1M1.3M. Primes and results attached.
I'll keep the remaining file for n=1.3M2M sieved to P=50T available if needed in the future.

 edit the page  if not yet done: insert the "RSieve" parameter  set the value like "y" for yes  choose "Show preview" > next to kvalue "Upload me!"  open link in new tab  choose you local file (not greater than 2MByte!), Wiki name is given  upload and close the filepage  choose "Show preview" on the kvalue page again, everything ok? > save  link is blue as "(sieve)" downloadable for everyone
