- - Riesel Primes k*2^n-1, k<300 [Part II] (https://www.mersenneforum.org/showthread.php?t=8621)

Releasing k=83 @ n=1.2M.
I reserve k=89 from n=1.12M based on latest RSP sieve file.

k=25 tested till n=2.49M
k=43 tested till n=2.47M
k=55 tested till n=1.38M
k=89 tested till n=1.14M
k=101 tested till n=2.71M
k=151 tested till n=2.59M
k=223 tested till n=2.79M

k=7 at 2670k
k=21 at 1525k
k=37 at 1760k
k=97 at 1500k
k=163 at 1120k

Proceeding with first four, while k=163 is stopped and released.

I release k=55 @ n=1.41M.

k=161 is complete to n=1500K, and the results are attached.

No primes were found.

k=19 tested to n=2.5M

I am thinking on exploring a k<300, but I wouldn't like redoing someone else's job. So I was trying to see which k's are available to pick one I like. I initially checked the tables/lists in [URL="http://www.15k.org/riesellist.html"]here[/URL] and [URL="http://www.15k.org/RPSotherRanges.html"]here[/URL] and then tried to match the data with the some of the last posts in this 17-pages (!!!) thread. However, even like that, not being able to find an updated complilation, I have the feeling I might be stepping in someone else's feet.
Could you point me to an updated list?

Also, where can I find a sieved list, or do I sieve myself? Thanks.

The first link you have there is our most updated list. Kosmaj updates that page every few weeks; with the holidays it has been a little longer than normal. With that delay in mind, you need only consult this thread's posts since the date posted at the top of that riesellist page.

Sieving has been done by the primesearchteam forum. You can either register over there and get the files from the source, or simply PM me your email address and the k you wish a sieve file for. Sieves are available from n=1 to n=3M and k=5 to k=10,000 at this time.

I join the quest!
I am taking k=165 starting @ n=1M.

I just updated the [URL="http://www.15k.org/riesellist.html"]k<300 status[/URL], including the latest reservation by otutusaus!
