More than Magic Squares
"In my younger days, having once some leisure (which I still think I might have employed more usefully), I had amused myself in making . . . magic squares." Benjamin Franklin, who made this comment in a letter written more than 200 years ago, was certainly not the first to experience the fascination of magic squares. People have been toying with these number patterns for more than 2,000 years. Typically, a magic square consists of a set of integers arranged in the form of a square so that the sum of the numbers in each row, each column, and each diagonal add up to the same total. If the integers are consecutive numbers from 1 to n ^2, the square is said to be of n th order. Here's an example of a magic square of the fourth order, made up of the first 16 integers. The sum of the numbers in each row, column, and diagonal is 34. There are 880 possible magic squares of the fourth order, not counting reflections or rotations of each pattern. One of the most remarkable of these squares is one that dates back to India in the eleventh or twelfth century. Notice that not only the rows, columns, and diagonals add up to 34 but also the corner 2 x 2 subsquares. And there's more! The four corner numbers add up to 34, as do the four numbers in the center. Other subsquares (such as 3 + 10 + 6 + 15) give the same result. It's also possible to find "split" subsquares and "split" diagonals that work: 7 + 2 + 14 + 11, and so on. In fact, there is an astonishing number of different ways to get the sum 34 out of this particular magic square.

Matrix Types Magic Square A magic square is a square array of numbers consisting of the distinct positive integers arranged such that the sum of the numbers in any horizontal, vertical, or main diagonal line is always the same number (Kraitchik 1952, p. 142; Andrews 1960, p. 1; Gardner 1961, p. 130; Madachy 1979, p. 84; Benson and Jacobi 1981, p. 3; Ball and Coxeter 1987, p. 193), known as the magic constant If every number in a magic square is subtracted from , another magic square is obtained called the complementary magic square. A square consisting of consecutive numbers starting with 1 is sometimes known as a "normal" magic square. The unique normal square of order three was known to the ancient Chinese, who called it the Lo Shu . A version of the order-4 magic square with the numbers 15 and 14 in adjacent middle columns in the bottom row is called . Magic squares of order 3 through 8 are shown above.

Merlin's Magic Squares
April 1998 In Merlin's Magic Square , an article that appeared in The American Mathematical Monthly in 1987, Don Pelletier explored the mathematical apparatus behind a toy game known as MERLIN . The game is not quite trivial and the mathematics is simple enough to provide an entertaining exercise in a Linear Algebra class. The original game is played on a 3x3 array of buttons that toggle between two states. The goal of the game is to achieve a target configuration of button states by pressing the buttons. The difficulty lies in that pressing a button alters its state but also toggles states of some neighboring buttons. The applet below generalizes the game in three ways:
  • Buttons are multistate,
  • The target configuration is modifiable,
  • The manner in which pressing a button affects its neighbors is selectable. The applet consists of two 3x3 arrays. On the left, the small one shows the target configuration. To modify the target configuration, click on the squares you want modified. On the right, a bigger one holds the puzzle itself and, if the

    Magic Squares    A "magic square" is a rectangular array of numbers, usually from 1 to n so that each column, row, and both diagonals have the same sum.  Other types of magic squares, with other shapes or special properties are common in recreational math.  You can find a very great number of examples of different squares and special features at the web site of Harvey Heinz with additional information on magic stars.
      The history of magic squares dates back to at least 1000 BC in China.  A Chinese book called Lo Shu (book of the River Lo) relates the story of how a magic square on the back of a turtle saved the city.  By the 2nd Century BC there were 4x4 magic squres appearing, often in connection with religious practice.  The Islamic/Arab mathematicians probably were introduced to the magic square from India, but they quickly developed squares of higher order.  One of the most famous illustrations of a magic square is in the famous Albrecht Durer woodcut, Melancholia.  The illustration and a blow up of the square can be seen at these links to the St Andrews University site.  Durer was a major contributor to the mathematics of art and is often credited with being the founder of descriptive geometry, yet he is probably known to most students, if at all, for this single woodcut. There are 880 different solutions to the 4x4 magic square, including the one in the Durer painting.

    Creating magic squares
    Have you ever given someone a problem which they can't solve after hours, when you can produce an answer in a matter of minutes? If not, here's your chance! A magic square is a N x N array of cells, each cell containing one of the first N positive integers, such that the sum of the numbers along any row, column and the two diagonals is a constant. De la Loubere was the French Ambassador to Thailand in 1687-1688 when he learnt the following method for odd values of N. Write 1 in the middle cell of the top row. Now keep writing 2,3,4,... in the up-right direction. If you reach the end of the square, `come out' on its opposite side. If you have to write on a used square, go down one cell. For example, here is a 7 by 7 magic square. This method gives only 1 magic square for any N. There are many others. Methods of creating even magic squares are known, but are not this elegant. Now, go and ask your best friend to create a 99 by 99 magic square... Back to Zimaths Issue 1.4

Practically all historians agree that the magic square had is origin in China centuries before the birth of Christ. The exact origin has been lost, but Oriental tradition holds that the Emperor Yu (c.2200 B.C.) was standing on the bank of the Yellow river when a tortoise appeared with a mystic symbol on its back.

    These are called magic squares. A magic square of order n (integers from 1 to n*n) has only one possible sum: (n*n+1)*n/2. Odd and even order squares must be constructed by different approaches. For odd orders, the most common algorithm is a recursive scheme devised by de la Loubere about 300 years ago. For even orders, one procedure is the Devedec algorithm, which treats even orders not divisible by 4 slightly differently from those which are divisible by 4 (doubly even). For squares with odd-length sides, the following algorithm builds a magic square: Put 1 in the middle box in the upper row. From then on, if it's possible to put the next number one box diagonally up and to the right (wrapping around if the edge of the grid is reached), do so, otherwise, put it directly below the last one. ...or even See archive entry knight.tour for magic squares that are knight's tours.

    Magic Squares A magic square is an NxN grid that contains all of the numbers from 1 to N (N-squared) in such a way that the sum of all of the numbers from any row, column, or diagonal equals the same number. For example, a 3x3 grid would contain all of the numbers from 1 to 9 (3-squared) such that, were you to add the numbers from any row, column, or diagonal, the sum would equal 15. Go ahead and enter an odd, positive number in the form field below, click the build button, and see for yourself. This application will generate the magic square for the dimension that you enter. That is, if you enter 3, it will display the 3x3 magic square. Dimension: This page was last updated Monday, February 8, 1999.

    Magic Squares
    Magic Squares may be perhaps the only area of recreational mathematics to which many of us have been exposed. The classic form of a magic square is a square containing consecutive numbers starting with 1, in which the rows and columns and the diagonals all total to the same number. I'll have to admit that I was never very much interested by magic squares, as opposed to other mathematical amusements, but a Mathematical Games column in Scientific American by Martin Gardner disclosed some new discoveries in magic squares that are of interest. The only magic square of order 3, except for trivial translations such as reflection and rotation, is: Some magic squares are very simple to construct. Magic squares of any odd order can be constructed following a pattern very similar to that of the 3 by 3 magic square: One can also construct a magic square by making a square array of copies of a magic square, and then adding a displacement to the elements of each copy based on a plan given by another magic square: thus, making nine copies of
