Interesting article on The Guardian's website about the new 'Magic Square' stamps that are going on sale in Macau feature the mythical turtle of Chinese legend 'lo shu' as well as some interesting maths. If you look at the dots on the turtle's back they'll add up to 15 horizontally, vertically and diagonally from each angle. More impressive still is the fact that the stamps themselves are being sold in this patter. You can buy one set worth 4,9 and 2 pacta, another with ones worth 3,5,7 and the final one with 8,6 and 1. Put them together and you've got the magic numbers.
