i found 70 primes for the k 16294579238595022365 which is 53#
i have taken it to 100k
i wont take it any further though because it is 4x slower than ks of about 1000
i also dont plan on taking 8413 any further

* - confirmed prime(s) previously found by others

A strangely dormant month for k < 333.3K!

For a more complete list, see the Riesel primes found and testing ranges web page here.

The following ranges searched are exceptions to the above that include ranges that have been previously searched by others:

k=111546435: -389K (all ranges tested)
k=115029915: -389K (all ranges tested)

Gary

Karsten,

k=19437, 102765, 3545685, 111546435, 115029915, 120023475, 290499495, 686701125, 775784295, 968911515, 1019370495, and 3428677395 are now all complete to n=400K with no gaps. A few more primes were found from the last status.

Karsten, you can see all of the primes at my status web page here.

These k's are now unreserved. They take too long to test!

i am planing to take a group of ks up from 10k to 35k starting from k=1653
does anyone know how many ks i should do i want it to take about as long as taking 5 average-weight ks up to 100k
also is anyone else doing the same because it looks like someone has done that up to that point

yes, he has done this in Jan.2008, no further efforts from him.
you can continue from k=1653.
try a frew to test the timings.

judging from my tests i will be able to finish all the unreserved ks <2000 to 35k
i just finished one k in 20 mins
