The graphic above is a 99 x 99 magic square. The value in each cell specifies the height of the cell. Areas that retain water on this mathematical surface are colored in blue.  If a cell is not colored in blue there is a downward path from that cell off the square.   It is now possible to write a unlimited amount of text on the surface of a magic square.  The pattern that the individual letters are typeset on is a zero retention bordered magic square.  The bordered magic square is constructed from a formula so there is no size limit. The formation of the individual letters in a 11 x 11 magic square is made possible by directed pair swapping.  The composite construction method for magic squares places the side specific drainage letters on the pattern.
