  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.


    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.
