Multiplication Magic Square


A square which is magic under multiplication instead of addition (the operation used to define a conventional Magic Square) is called a multiplication magic square. Unlike (normal) Magic Squares, the $n^2$ entries for an $n$th order multiplicative magic square are not required to be consecutive. The above multiplication magic square has a multiplicative magic constant of 4,096.
