For many years, recreational mathematicians have been
searching for a 3x3 magic square of nine different square numbers,
with all three rows, columns and the two long diagonals summing to
a constant total. No such matrix has been found, but one comes
close and its skeleton is shown here.
It has a constant sum of 3249 (572) along each of the
three rows and columns, but not along the two diagonals. Given
442 in the centre cell, can you find the other eight
square numbers?
