Finally, at 4 times the expectation, I have found the largest known prime
5953176232124*50# + 9564671 + 0, 2, 6, 8, 12, 18, 20, 26, 30, 32, 36, 42, 48
It has 31 digits like the old record. After optimizing my program and reducing
the target from 32 to 31 digits due to impatience, the expected time was 60
hours but I still had bad luck. A new record tuplet search is running but I'm
not publishing expectations this time.
The tuplet was found with my own sieve and the GMP library for prp testing.
All primes were proved with Tony Forbes' VFYPR.
