In the latest update of www.multimagie.com, a new smallest known magic square of powers. A 144x144 magic square of 7th powers, constructed by Toshihiro Shirakawa. Magic sum = 3141592653589793238462643383279502884197169399375105. Amazing, all the digits of its magic sum are exactly the 52 first digits of Pi!
Was the magic square constructed with that sum as a constraint so that, e.g. one could just as easily use the first 52 digits of e or phi; or is there really some deep connection with pi? -- Mike Stay - metaweta@gmail.com http://www.cs.auckland.ac.nz/~mike http://reperiendi.wordpress.com
