Extractions: Carré trimagique 128x128 Gaston Tarry (Villefranche de Rouergue 1843 - Le Havre 1913) Pour La Science Pour connaître l'histoire du carré trimagique 128x128 de Gaston Tarry, se référer à notre article paru dans le numéro 286 d'août 2001 de Pour La Science En juin 2002, nous avons reconstruit le carré de Tarry pour le vérifier. Tarry avait prouvé la trimagie de son carré, mais n'avait calculé que la 1ère colonne. Nous l'avons entièrement calculé : nous pouvons maintenant confirmer que le carré est vraiment trimagique !

Monster Cubes I dedicate the tetramagic cubes to gaston tarry and André Viricel. gaston tarry,inventor of the tetramagic term, was the first person to have constructed http://members.shaw.ca/hdhcubes/boyer-monster.htm
Extractions: Harvey Heinz Nov. 27, 2003 Christian Boyer, France, May 13 rd I have the pleasure to announce 7 new important multimagic results: the first tetramagic cube , so better than my previous trimagic cubes the first perfect tetramagic cube , means all its diagonals and triagonals are tetramagic (and probably the biggest magic cube ever constructed !) the 3 first bimagic tesseracts , means four-dimensional bimagic hypercubes the 2 first trimagic tesseracts , one of them being also the first perfect bimagic tesseract (means all its diagonals, triagonals, and quadragonals are bimagic)
Magic Squares In 1905, a 128 by 128 magic square was devised by gaston tarry where the numbers,their squares, and their cubes were all magic; this is called a trimagic http://members.shaw.ca/quadibloc/math/squint.htm
Extractions: Home Other Mathematics 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

Born in Villefranche de Panat , Aveyron , he studied mathematics at high school before joining the civil service in Algeria . He pursued mathematics as an amateur , his most famous achievement being his confirmation of Leonard Euler Graeco-Latin square was possible.
Extractions: M ultimagic Squares Multimagic squares are regular magic squares i.e. they have the property that all rows, all columns, and the two main diagonals sum to the same value. However, a bimagic square has the additional property that if each number in the square is multiplied by itself (squared, or raised to the second power) the resulting row, column, and diagonal sums are also magic. In addition, a trimagic square has the additional property that if each number in the square is multiplied by itself twice (cubed, or raised to the third power) the square is still magic. And so on for tetra and penta magic squares. This page represents multimagic object facts as I know them. Please let me know if you disagree or are aware of other material that perhaps should be on this page. Notice that I have adopted the new convention of using 'm' to denote order of the magic object. With the rapid increase in work on higher dimensions, 'n' is reserved to indicate dimension. Table showing a chronological history of multimagic squares (and 1 cube). Walter Trump announced the successful completion of this square on June 9, 2002!
Graeco-Latin Squares In 1901, gaston tarry proved (by exhaustive enumeration of the possible cases)that there was no GraecoLatin square of order 6 - adding evidence to Euler s http://buzzard.ups.edu/squares.html
Extractions: A Latin square of order n is a square array of size n that contains symbols from a set of size n. The symbols are arranged so that every row of the array has each symbol of the set occuring exactly once, and so that every column of the array has each symbol of the set also occuring exactly once. Two Latin squares of order n are said to be orthogonal if one can be superimposed on the other, and each of the n^2 combinations of the symbols (taking the order of the superimposition into account) occurs exactly once in the n^2 cells of the array. Such pairs of orthogonal squares are often called Graeco-Latin squares since it is customary to use Latin letters for the symbols of one square and Greek letters for the symbols of the second square. In the example of a Graeco-Latin square of order 4 formed from playing cards, the two sets of symbols are the ranks (ace, king, queen and jack) and the suits (hearts, diamonds, clubs, spades). Here is an example of a Graeco-Latin square of order 10. An Order 10 Graeco-Latin Square (10K) The two sets of "symbols" are identical - they are the 10 colors: red, purple, dark blue, light blue, light green, dark green, yellow, gray, black and brownish-orange. The larger squares constitute the Latin Square, while the inner squares constitute the Greek square. Every one of the 100 combination of colors (taking into account the distinction between the inner and outer squares) occurs exactly once. Note that for some elemnts of the array (principally, but not exclusively, along the diagonal) the inner and outer squares have the same color, rendering the distinction between them invisible.

Bodenmiller (19th century re-discovered the theorem about the midpoints of diagonals of a quadrilateral now also ascribed to Gauss. Henri Brocard (1845-1922): discovered a number of properties associated with the points, triangles and circles now named after him. Giovanni Ceva (?1647-?1736): discovered theorems about points on the sides of a triangle (see glossary); the one for collinear points is now ascribed to the first century Alexandrian geometer, Menelaus. Leopold Crelle (1780-1855): engineer and editor of famous mathematical journal; he discovered various properties of triangles including the points now named after Brocard. He claimed that "it is wonderful that so simple a figure as the triangle is so inexhaustible". Euclid (c300 BC): author of the Elements the influential systematic account of geometry including many theorems about triangles. Leonhard Euler (1707-1783): prolific Swiss mathematician who established that certain special points of a triangle lay on a line - now named after him.
