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.

Default I am recovered and found another prime

Hello,
I found another prime for k=561973.
This one is 561973*2^639231-1
The number has 192434 digits.
Currently i am testing k=561973 for n=700000 to 800000.
This might take a few days.
I am feeling better now.

Default 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?
