The largest known Proth prime

[nuutti]

is 5*2^1,320,487

Server is assigning n values 1,334,xxx right now so it starts to look like the next new prime we will find will be the largest known proth prime.

The sixth largest known prime is the largest nonmersenne prime.
It is 1478036^65536+1 and it is 404337 digits long. n values
larger than 1,336,000 will mean that we are checking numbers that are larger than this number.

The fifth largest known prime is 2^1,398,269-1 found by GIMPS in 1996. We will reach this magnitude very soon. Probably before the weekend.

And according to some estimates
between 2^20 = 1,048,576 and 2^21 = 2,097,152 there are roughly 2.2 primes.


So the next one will be the big one and we will find it during this year (unless we are very unlucky).

Looking forward to it! :cheers:

By the way Nuuti, I vaguely recall a previous post from you explaning your location, but I don't remember its content. Why, exactly, do you claim Helsinki as a suburb of Chicago? :confused:

[nuutti]

Well.
I actually live both in Helsinki (Capital city of Finland, small Northern Europe Country) and in Chicago, Illinois, USA. I mean that I have apartments in both cities. True reason is that my wife is doing Ph.D (in economics) in University of Chicago, Illinois and I am doing my mandatory military service right now so I have to be in Finland until next spring and after that I will move permanently to Chicago, Illinois.

Yours,

Nuutti

Interesting (both bits of info). ;)
