Congratulations to DeleteNull for finding the 2.6 million digit mega-prime 273809*2^8932416-1 and eliminating k=273809 from the Riesel Problem! 49 k's remain.

This is PrimeGrid's 60th mega prime of 2017, our 195th mega prime overall, and the 15th k eliminated by PrimeGrid from The Riesel Problem. This is also DeleteNull's second mega-prime, as well as the second k he's eliminated from one of the our conjecture projects. (Click here for the full list of DeleteNull's prime discoveries at PrimeGrid.)

So why does a k get eliminated if a prime is found? Is that the only one that is possible from it?

Edit: pardon my ignorance, I just read about The Riesel Problem and it answered my question.

Congratulations to DeleteNull for finding the 2.6 million digit mega-prime 273809*2^8932416-1 and eliminating k=273809 from the Riesel Problem! 49 k's remain.


Many thanks to all who have helped to make this possible! I am the lucky one who got this special workunit to eleminate that k.

And 49 k remain, so there will be other lucky (and patient) finders in the future ;)

Nope, it's a -1 (Riesel), not Proth ;)

Ha ha.

But it depends on the perspective. If you write the candidate as:

N = k·2^n - 1


then you are right, we see a minus one.

But if you express instead, in terms of N, the number that is smooth to factor, that is N + 1, so for example in the help for PFGW, you can see:

-t currently performs a deterministic test. By default this is an N-1
test, but N+1 testing may be selected with '-tp'. N-1 or N+1 is
factored, and Pocklington's or Morrison's Theorem is applied. If 33%
size of N prime factors are available, the Brillhart-Lehmer-Selfridge
test is applied for conclusive proof of primality. If less than 33%
is factored, this test provides 'F-strong' probable primality with
respect to the factored part F.


And in Caldwell's Primality Proving pages, the term N+1 test is used in the same sense.

So Riesel is an N+1 test.

+1 to me.
