A Magic Square of order n is an arrangement of the numbers from 1 to n^2 (n-squared) in an n by n matrix. The sum of any row, any column, or any main diagonal must be the same. The smallest non-trivial case is of order 3.
The same idea can be extended to other shapes such as stars, cubes, circles, and so on. These are called Magic objects.
Please submit sites related to the history, definition, description, construction, and examples of Magic Squares and other objects, such as cubes, stars, etc.
Sites related to the mathematical treatment of the subject are not numerous and will be much appreciated.
Only sites directly related to magic squares or other magic objects will be accepted, otherwise it will probably better fit in a different category, such as /Science/Math/Recreations.
This category accepts submission of sites in English. Non-English only sites should be submitted to the corresponding language(s) of the World category.
