A black and white image of D4 transformations acting on a square

The image above is a composite of stills from an animation that illustrates how these 4 rotations and one reflection allow a one-eighth segment to cover the entire area of a square. Applied to a magic square matrix, this allows certain positions in the matrix to be seen as unique.
