That's what I did. The code was deleted automatically and reassigned to Dennis Schreiber. That prime is now sorted. I suppose I had better sort out the other problems. I hate wasting his time this much. I will be more careful in future.

815*2^790042-1 is prime
I have found more primes this year already than last year with much less testing.

Amazing. After an n=14K range with only 1 prime from n=765K-779K, we've had 6 primes in an n=4K range from 779K-783K; 5 already reported and 1 yet to report by Vaughan.

The best run I've ever had so far:

5 primes at n~780k in a 3.5k n-range!

Looking here those 5 primes were found on 5 consecutive days: Feb. 11th to 15th.

Good average per day! Anyone to calculate the odds for such find?
