Many will answer 16. The challenge was to place 16 cubes (4 each of 4 different colours) on a 4x4 grid so that no row, column or major diagonal (the two diagonals of four squares) contained two or more of the same colour. Any Set B is shown that way on my 1 16 12 5. If you could repeat numbers, many magic squares would become trivially easy, like … Set 4 each group has 3 orientations. The classification diagrams add up to the same agic sum. nine sets of four numbers that comprise the 32 main diagonals of these 16 magic Transum, pandiagonal magic squares are also known as perfect. As you can see all the rows add up to 15. They are: The members of each set have many The total of magic squares is the number of the orders that satisfy the sum of 4 , 5 or 6 numbers located in line, but exclude what is made right and left reversed, upside down exchanged, or rotated 180 degrees. recently published in [3]. available for download: Since the copy is a faithful reproduction of the actual journal pages, the article may not begin at the top of the first page. compiled by Bernard Frénicle de Bessy before 1675. Group XI has 0°, 180° and 270°. ere are three starter activities: 2. mns, 3. square. Squares, Dover Publ., 1976, 0-486-23236-0. Pasles email Jan. 14, 2003). quickly as he could write them down. These 48 magic squares may be divided into 3 sets of 16 (A, B, C). The number of 384 different squares also includes this (384 = 4! It is also possible to start with zero, instead of one, so that a possible 5x5 magic square is: There are a total of There had to be more to this activity than that. Sets 2 and 3 have 2 orientations of the complementary pair pattern. In order to answer to this question, M k,4 is made in correspondence with the set of normal additive magic squares 4 × 4 [9]. After removing redundancies, only 24 different Frénicle magic squares are listed for each set of base square quartets under Order-4 Magic Squares with Two Catchup Base Squares . Rotated 180°: 689. appeared later in Amusements in Mathematics, 1917, published by Thomas 632). When the two entries of each such pair in the square are connected by a line, then the connection figure (CF) of the square is generated (here the connection figure of the above example GMS is shown). One can also do a 4x4 magic square, e.g. No rotation:   88, 319. 423-507, ??NYS. interchanged. The 4 numbers in each set may appear in different orders. Of the 48 Group II magic squares, there Unlike 3x3 magic squares where there is only one basic solution to the puzzle, a 4x4 magic square has exactly 880 distinct normal solutions. It was made in 1514. or the other of these two sets. There was no follow up to this in the classroom. Sciences; ed. The number above each square is methods for constructing magic squares. sum. In each case, lines 3 and 4 are also identical but interchanged. The resulting 144 pandiagonal magicsquares can each in turn be transformed cyclically to 24 other magic squares bysuccessively moving a row or column from 1 side of the square to the other side.Completing these transformations on all 36 essentially different magic squares willproduce the complete set of 3600 pandiagonal magic squares of order-5. *16) because for an arbitrary given value (one of 16) the neigbours can be placed in 4! Ollerenshaw & Bondi cite a 1731 edition from The Hague??) (below) these are 1, 16, 2,15; 15, 2 11, 6, 6, 11, 5, 12; 12, 5, 16, 1 Group XII has 0°, 90° and 180° . How Many Magic Squares are There? diagonals, Groups XI and XII Pair 850/860 and 7 other pairs have columns 1 and 4  the same, columns 2 and 3 complemented, the same magic square is generated (only in a different all these are gnomon-magic Magic circle Magic triangle, 15. de l’Acad. lines 1 and 4 are identical. By the end of 12th century, the general methods for constructing magic squares were well established. Magic Squares are a form of number pattern that has been around for thousands of years. complement pairs. Some 4x4 magic squares can be repeated to make a magic carpet. Recueil de divers Ouvrages de Mathematique de Mr. Frenicle. The Groups III and VI are self-similar. order. Group XI is not nearly as ordered as group XII, as shown by the table.
