  2. Associative magic square - Wikipedia

    en.wikipedia.org/wiki/Associative_magic_square

    The number zero for n = 6 is an example of a more general phenomenon: associative magic squares do not exist for values of n that are singly even (equal to 2 modulo 4). [3] Every associative magic square of even order forms a singular matrix, but associative magic squares of odd order can be singular or nonsingular. [4]

  3. Magic square - Wikipedia

    en.wikipedia.org/wiki/Magic_square

    The smallest (and unique up to rotation and reflection) non-trivial case of a magic square, order 3. In mathematics, especially historical and recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same.

  4. Multimagic square - Wikipedia

    en.wikipedia.org/wiki/Multimagic_square

    The first 4-magic square was constructed by Charles Devimeux in 1983 and was a 256-order square. A 4-magic square of order 512 was constructed in May 2001 by André Viricel and Christian Boyer. [1] The first 5-magic square, of order 1024 arrived about one month later, in June 2001 again by Viricel and Boyer. They also presented a smaller 4 ...

  5. Freudenthal magic square - Wikipedia

    en.wikipedia.org/wiki/Freudenthal_magic_square

    The squares discussed so far are related to the Jordan algebras J 3 (A), where A is a division algebra. There are also Jordan algebras J n (A), for any positive integer n, as long as A is associative. These yield split forms (over any field K) and compact forms (over R) of generalized magic squares.

  6. Magic constant - Wikipedia

    en.wikipedia.org/wiki/Magic_constant

    The magic constant or magic sum of a magic square is the sum of numbers in any row, column, or diagonal of the magic square. For example, the magic square shown below has a magic constant of 15. For a normal magic square of order n – that is, a magic square which contains the numbers 1, 2, ..., n 2 – the magic constant is = +.

  7. Magic cube - Wikipedia

    en.wikipedia.org/wiki/Magic_cube

    An example of a 3 × 3 × 3 magic cube. In this example, no slice is a magic square. In this case, the cube is classed as a simple magic cube.. In mathematics, a magic cube is the 3-dimensional equivalent of a magic square, that is, a collection of integers arranged in an n × n × n pattern such that the sums of the numbers on each row, on each column, on each pillar and on each of the four ...

  8. Magic series - Wikipedia

    en.wikipedia.org/wiki/Magic_series

    A magic series is a set of distinct positive integers which add up to the magic constant of a magic square and a magic cube, thus potentially making up lines in magic tesseracts. So, in an n × n magic square using the numbers from 1 to n 2, a magic series is a set of n distinct numbers adding up to n(n 2 + 1)/2.

  9. Magic circle (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Magic_circle_(mathematics)

    A magic circle can be derived from one or more magic squares by putting a number at each intersection of a circle and a spoke. Additional spokes can be added by replicating the columns of the magic square. In the example in the figure, the following 4 × 4 most-perfect magic square was copied into the upper part of the magic circle. Each number ...
