Mersenne Prime Award of USD $3,000.00
Awarded to a GIMPS Participant for each new Mersenne prime discovered after August 23, 2008 and having fewer than 100,000,000 (decimal) digits. Rules in addition to the General Award Rules:
  • The award is presently $3,000. A maximum of $5,000 USD and minimum of $1,000 will be awarded, as determined by the GIMPS board of directors from actual and forecast award funds availability. GIMPS may, at its sole discretion and without notice, change the award amount or retroactively increase certain previously-awarded Research Discovery Awards up to the maximum amount.
  • Verification may take several weeks. No money will be awarded until the discovery is independently verified, and the award money is available after GIMPS annual operating expenses.
  • In the unlikely event that an identical qualifying prime is discovered at about the same time by two or more Participants, then the winner will be the first to either send their result to the GIMPS PrimeNet server or to email their results to GIMPS.
It's somewhat interesting to note that this isn't (like the smaller prizes last time) limited to being discovered before the 100M digit prime, only that it's under 100M digits.

I was interested in the admission that it will take GIMPS "12-15 years"
to reach 100M digits at the current rate of participation.

It looks like we are #29 on Time Magazine's 50 Best Inventions of 2008:
http://www.time.com/time/specials/pa...854157,00.html

I wonder if it was a fluke they picked 29 since it is also prime, or if it just worked out that way?

The 2n-1 error appears again (not to mention the reference to a UCLA "team")...

The first is a typesetting to web issue, their picture is great and has it right.
There was a "team" at UCLA, they found the number, as much as it says was correct.

Well, I haven't heard about any other team members. I got the impression Edson Smith was solely responsible for installing Prime95, unless you want to count administrative approval as being part of the team.

The headline "45th Mersenne Prime Earns #29 on Time's Top 50 Best Inventions of 2008" has been posted on www.mersenne.org (which by the way has merged with v5).

But even if they are a team, their maths stinks (or is it the maths of the writer of the article ?) : "It's a number that is so long that if you typed it out at 10 characters per inch, it would stretch 20 to 30 miles long, depending on what font you were using." No if typed out at 10 c / inch it will be 52 miles whatever the font (because they defined the font as using an inch for 10 characters. Then they repeat the typesetting fault seen in other articles : "2p-1" instead of "2p-1" or "2^p-1" or even "2**p-1". Two other pearls in the article : "In fact, tens of thousands have participated in the search by downloading a free program from GIMPS, which keeps track of which numbers are tested and eliminated, and sends out untested candidate numbers to the GIMPS community for factoring. The process of factoring one number can take a computer as long as two months, Smith explained. But joining forces via the Internet makes the search possible." and"GIMPS tested the number by factoring it using a different algorithm on various kinds of computers. "We had to sweat it out for two weeks until they verified it," Smith said.", they factored it initially and during the verification run ?

The article was better than average, though. It turns out the number was found on the same type of machine that I am typing on.
