Holy Saint Lucas! 2 new primes? (M45 related, and M47)
Did I miss something? The status page reports 2 unverified primes!

Indeed. But I don't find any decoy exponent with the fake residue 0xB6C801... in cleared.txt like we should get if there were a new prime.

Perhaps this thread explains it?

I doubt it. Many people must have used Prime95 to test know Mersenne primes before, and they never showed up as unverified new primes so far.

I hope that's not all it is, but admittedly it does seem rather unlikely that while M45 is verifying we'd find M46.

You know what's really odd?
I had a feeling that this would happen not long after M45 was reported. I guess I need to develop my primepredicting powers. OK, maybe I read way too many comic books.

I suppose the worst case scenario is that someone just missed out on a large share of $100k.

I think there are three possibilities: 1. Some really did find a new prime. 2. Someone (who is not on the official verification team) guessed the exponent of M45 and independently tested it on a highperformance system. 3. Someone used an old version of Prime95 that caused false positives. I have a strong feeling that #2 is the case, but I'm really hoping it's #1.
