  1. lol, i’m having a diificult time solving this..but still it is very challenging too..btw

    Thanks for the info..there’s so much information there and very helpful too..i’ve bookmarked this blog too…and even though i’m too busy doing research and too busy on my everyda work, i’ve always spend some of my time visiting here…nicely put and hey, you should start writing books bro..;)

  2. Sol,

    Yes, this is the lo-shu, which according to Howard Eves (An Introduction to the History of Mathematics) is the oldest known example of a magic square. I will have a few more magic square puzzles and the legend of the lo-shu coming up, but a death in the extended family plus the busy-ness of the season have thrown my posting schedule all out of whack.

    Kpli,

    Are you for real? Normally I delete spam comments, and yours has enough effusive yet vague praise to look like one. But perhaps it is just a language barrier, so I will let you stay. Warning to other readers: The link leads to a foreign-language “We’ll do all your homework for you” sales page. If you are looking for that sort of thing, I suggest you find one with a better mastery of English.
