Slightly off-topic, but it bugs me that the article feels obliged to contain a picture of the number. Firstly, why the hell would you want to display plain text as a picture? Secondly, if I click through to the source, I get a slightly better picture. Did IHC take a photo of the original website with their phone camera and upload it? Mind is boggling. Encouraged by the better quality picture on geekosystem I decided to click through to THEIR source. And there's a plaintext version. Kudos to <a href="http://www.futilitycloset.com/2012/01/08/math-notes-76/<...; for having a modicum of common sense.
