Excellent! Nice prime Ian. You were due for one on that huge n=100K-200K effort you have going for numerous bases.
But...another 1k base. Ugh!

Riesel base 476 is proven with a nice top-5000 prime:
49*476^72833-1 is prime! On a side note, the proof of this base now completes a run of five straight proven Riesel conjectures in numeric sequence. |

Dmitry found 14*333^69297-1 is prime.
I'm currently following up on whether he is searching the other 2 remaining k's for this base. |
