Magic-Multiplier-Square-6-and-5, originally uploaded by d-cecil.

Some latin squares and graeco-latin squares can be made into a magic multiplier square by using two or more relatively prime positive integers (here 6 and 5) and coding the latin or graeco-latin square letters and numbers as we have done here with A replaced by 6 to the 1st power, etc.
