2005-10-14 : Another MUST HAVE item !

Isn't the internet a rewarding place ? It turns out that one can buy posters of extremely large Mersenne prime numbers !

Choose from old favourites like (26972593)-1, (213466917)-1, or if you're into more fashionable and contemporary numbers, there's the recently discovered (225964951)-1.

Make your Christmas list a hallowed ground ! Go here to buy a piece of paper with a lot of numbers written on it really small.

It intrigues me that if you buy 2 or more of these posters, how do you tell which is which ? And how the hell do you know if they're making it up or not ?
