Re: [math-fun] Multiplicative Magic Squares

BTW, any additive magic square can be turned into infinitely many multiplicative ones just by exponentiating by a common base. On 9/21/05, ed pegg <ed@mathpuzzle.com> wrote:

Are multiplicative magic squares well studied? For example, using dots merely as spacers, the following has a multiplicative constant of 55440.

231 .40 ..3 ..2 ..6 ..1 132 .70 ..4 .21 .20 .33 .10 .66 ..7 .12

Is there a list of smallest multiplicative constants for various NxN squares somewhere?
