A method and apparatus for generating a plurality of unique configurations of indicia is provided. A first set of indicia is provided, including a plurality of first groups of indicia. Then a second set of indicia is provided that has a plurality of second groups of indicia. The first set of indicia is then combined with the second set of indicia in a pairwise fashion, wherein a number of the first groups of indicia is relatively prime in relation to an number of the second groups of indicia.
