Is this correct - no primes yet found for the Prime Sierpinski problem?

Check out http://www.primegrid.com/stats_psp_llr.php .

Given a specific k, which number for n possibly returns a prime?

What is the smallest number for n? Or the largest number for n?

Is it anything else than 12715413 (min for n in progress) or 13229237 (max for n in progress) assuming k=222113?

Just wondering.


There are only 8k's left. For the other ones a prime was found. max n can be much higher than viewed yet.
