Do we know who's going to make the announcement? (So I can actively look for the article)

Default Naming of new primes

So:

2^37156667-1 is candidate to be M45.
2^43112609-1 is candidate to be M46.


Till we have checked all exponents before, for sure...

And Chris has not yet updated his page !

It would be nice, from a mathematical point of view, if GIMPS were to
stop looking for NEW primes (now that we have a prime > 10M digits)
and instead were to work on filling in the GAPS.

Also, these primes are quite interesting from a mathematical point of view.

Before revealing what makes these two so interesting, I will give others
a chance to suggest the reason.

Congratulations and thanks to everyone!!!! GIMPS is a group effort. While a few lucky discoverers get the glory, they couldn't have done it without all the hard work put in by the rest of you.

You are hereby ordered to have a celebratory drink tonight.

Thanks too for your patience during the verification and announcement process.

Not unexpectedly, they are not a part of a twin prime pair and don't disprove the NMC.

5^2*859 | 2^37156667-3
297253337 | 2^37156667+1

191 | 2^43112609-3
86225219*5259738299*5949540043*12482997260297 | 2^43112609+1

Congrats everyone!

Wilco! Haven't decided whether it will be Tomato Juice spiked with Tobasco or the Plzner Prazdroj in the fridge.

I noticed that at Wikipedia, the August prime is listed as #47, and the September prime is #46. I suppose this is the way they'll always* be listed now.

M46 is the lowest known prime with more than 10M digits, but M47 won the prize!


*note: "always" is not the correct term, since new mersenne primes less than M47 may still be found.
