Cool k=37

37·26660841-1 (2,005,115 digits)

(Note: This was in context of the Riesel-like-base1024 conjecture, so only n ≡ 1 (mod 10) were tested up to n=6700000.)

Congrats on your bi-mega

It is amazing that such a prime was verified in 3.61 hours by CC @ UTM.

Ah, heck. It was only luck.

But: "The more I practice, the luckier I get". (Which might be one of those things that Yogi Berra also never said. The authorship is disputed, as is the case with any bon mot including "Prediction is very difficult, especially about the future")
