Wikipedia has it but with no citation;
I just dropped a note at the discussion page http://en.wikipedia.org/wiki/Talk:Prouhet-Tarry-Escott_problem of the wikipedia page, http://en.wikipedia.org/wiki/Prouhet-Tarry-Escott_problem asking for the reference. As the page was created only 1 month ago there is a good chance that we get an answer soon. I dropped also a note about the relation to the 3x3 magic square. Christan, if this ok for you, I would/should give credit to you for that... Anyway, a really fascinating peace of math-fun!! Christoph
