12*186^112717-1 is prime!

Conjecture proven.

Considering that this was one of the lightest weight Riesel conjectures, it is nice to get it off the list.

A HUGE congrats from all at CRUS for finally breaking the proven conjecture record. With CK=2414, this breaks the 3+ year old standing record of CK=1886 set by S36!! It also smashes the biggest prime found by CRUS by more than 100K digits!

Yippee!!

I should have offered a hearty congrats to Ian at the time for this prime. So...congrats Ian! At the time, this was the 2nd largest prime ever found by CRUS and only ~10K digits smaller than the prime to prove S23, also found by Ian. Not only that, it also gave him CRUS's 3 largest primes.
