The Parker Square is an example of a Semi-Magic Square devised by Matt Parker in 2016. This particular Magic square is special in regards to how each number is a perfect square. The square is, however, regarded as only a Semi-Magic square, because the positively sloped diagonal does not in fact add to 3051 as all other sides do. Instead its summation is equivalent to 4107. The Parker Square is significant because it is one of the closest attempts to finding a perfect Magic Square in which all of the numbers are perfect squares.
