On 5 October 2013, 19:06:07 UTC, PrimeGrid’s The Riesel Problem project eliminated k=398023 by finding the mega prime:
398023*2^6418059-1
The prime is 1,932,034 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 23rd overall. This is the largest prime found in The Riesel Problem and PrimeGrid's 10th elimination. 54 k's now remain.
The discovery was made by Vladimir Volynsky (Grey) of Russia using an Intel(R) Core(TM) i7- 3820 CPU @ 3.60GHz with 16 GB RAM running Windows 7 x64. This computer took 12 hours 43 minutes to complete the primality test using LLR. Vladimir is a member of the Russia team.
The prime was verified on 8 October 2013, 00:48:18 UTC, by Wolfgang Schwieger (DeleteNull) of Germany using an Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz with 16 GB RAM running Linux. This computer took 10 hours 4 minutes to complete the primality test using LLR. Wolfgang is a member of the Nemesis Germany team.
For more details, please see the official announcement.

Nice, we need more of these Challenges :) | |

The most incredible thing about this find is that it was not cncr04s who found the prime nor was he the double-checker.
It only proves that finding such primes is more like a lottery: you can buy almost all tickets but a lucky one with just one ticket will collect the prize. | |

But he found one , about same time you wrote this message :)
And it is even bigger one than found in challenge :)
So you can expect again: new sieve file and new official statement :))

All true. Jim's theory is that the act of creating and releasing a new sieve file altered the reality of mathematics and caused a new prime to pop into existence just to make him repeat the work. Iain thinks that primes are like London buses: you wait forever for one to come, and then two come at once. I tend to side with Iain, except I think primes are more like New York buses.
Anyway, yes, there's another prime (found just after the challenge), yes, cncro4s is the prime finder, and yes, there will be another sieve file.
