[QUOTE=ixfd64;327999]I wonder if Perfectly Scientific, Inc. is still going to produce those Mersenne prime posters. It would be sad if the tradition ended with Dr. Crandall's passing.[/QUOTE]From an e-mail exchange with an employee:
[QUOTE]<Crandall is dead> The company is therefore in a transitional period and we are not able to create a new poster at this time. We hope to be able to soon.[/QUOTE]

From ComputerWorld:

GIMPS noted that the grid that Cooper used for the discovery had 360,000 CPUs peaking at 150 trillion calculations per second.

The register is also not far away, they said the mersenne numbers are x^2-1 (!?!?) and corrected that after about 10 comments... These articles (and comments) are always fun to read.

Slate's guy was doing, indeed, a much better (and poetic) job!

[QUOTE=Prime95;327963]I like this one best, I'll use it next time.[/QUOTE]
In case you're still open to other suggestions, I think the verb "double" is understandable by people with no mathematical training. So how about a description like "start with 1, then keep doubling 57885161 times, and finally take one away"?

Especially by Davieddy on a Saturday night.

For anyone able to receive Dutch television channels:
Hendrik Lenstra will be appearing as a guest on the program
"De wereld draait door" this evening (Wednesday 6 February 7.30-8.25 pm
CET = UTC+1) on the channel Nederland 3 in order to answer questions related to this discovery.

Thanks, I'll watch that with you when you get home.:smile:

Been waiting four long years to see a "1" in the left-most column of [URL="http://www.mersenne.info/exponent_status_tabular_delta_7/2/50000000/"]this report[/URL]! :smile:
