And another one for k=111:

111*2^1946322-1 (585904 digits)

1293*2^1332159-1 (401023 digits)

4069*2^1093101-1 (329060 digits)

4065*2^1097330-1 (330333 digits)

191*2^4203426-1 (1265360 digits)

My first one (and a quarter) million digits prime! :smile:

Congrats Thomas :banana:

Thanks, Paul!

Actually I had a similar experience like Peter with his k=9/n=4M prime:
I had temporarily stopped this k at n=4.2M a few months ago and, surprisingly, the prime appeared just one day after restarting.

Hi Thomas,

Congrats on that GREAT prime!
It will be our 2nd largest, and 40th largest of all times.
