... permutation R (12 ) C (12 ) S (12 ) squares with row of 032X and 023X are equivalent to squares with row of 013 X and 031X Thus only squares with row of 012 X, 021X, 013 X, or 031X are considered (figure 16 ) • ... row, column and symbol permutations K4 (3, 1, 2) = [10 ] and using the Singleton bound A4 (3, 1, 2) = 16 We completely catalogue (3, V, 2)4 codes where V = 8, 9, 10 , 11 , 13 , 14 , 15 , 16 and provide ...
