Magic Square of Squares

 

A square is magic if each of the rows, columns, and diagonals add up to the same total.  So, for example, the square

    25    4   19

    10   16   22

     13   28    7 

is magic, since every row, column, and diagonal adds up to 48.  Of the nine entries, three (4, 16 and 25) are perfect squares.

The problem is to find a 3 by 3 magic square all of whose entries are distinct perfect squares, or prove that such a square cannot exist.
