 2022-04-24, 23:05 #475 kar_bon     Mar 2006 Germany 3·23·43 Posts What another mess! Stopping one k-value and beginning another, again not from n=1 (although the primes for k=16545165 for n<10k are already known) and also missing your posted prime 1928345*2^120782-1 in the other thread but posting your primes again in this thread! Your data and results are not reliable, so I will not grant you write permissions to the Wiki. Bye.

Currently i am testing k=561973 for n=700000 to 800000. This might take a few days. I am feeling better now. Last fiddled with by Harklo73 on 2022-05-19 at 18:20
 2022-07-03, 01:59 #477 Harklo73   Jan 2022 13 Posts Update on k=561973 Hello, I tested the range n=700000 to 800000 for k=561973. I did not find any primes unfortunately so I am continuing the range for n=800000 to 900000. This might take me a couple of weeks, the numbers are getting bigger :)

Small question: did you sieve your range before starting the testing?
