Analogously, 3-D magic squares in which solid pieces combine to form a constant 3-D target can also be found.
I have one before me as I write, the target of which is a cube; see Figure 3.
Likewise geomagic squares using higher dimen- sional entries also exist, if less easy to visualize.
By the dimension of a geomagic square we refer to the dimension of its entries. For a formal definition of geomagic squares, see http://www.OeomagicSquares.com/, which also includes a large gallery of geomagic squares exhibiting a rich variety of special properties.
