  1. linear OOA(492, 50, F49, 3, 2) (dual of [(50, 3), 148, 3]-NRT-code), using
  2. linear OOA(4913, 1921601, F49, 3, 4) (dual of [(1921601, 3), 5764790, 5]-NRT-code), using
  3. linear OOA(4929, 1921601, F49, 3, 8) (dual of [(1921601, 3), 5764774, 9]-NRT-code), using
    • OOA 3-folding [i] based on linear OA(4929, 5764803, F49, 8) (dual of [5764803, 5764774, 9]-code), using
      • discarding factors / shortening the dual code based on linear OA(4929, 5764805, F49, 8) (dual of [5764805, 5764776, 9]-code), using
        • construction X applied to Ce(7) ⊂ Ce(6) [i] based on
          1. linear OA(4929, 5764801, F49, 8) (dual of [5764801, 5764772, 9]-code), using an extension Ce(7) of the primitive narrow-sense BCH-code C(I) with length 5764800 = 494−1, defining interval I = [1,7], and designed minimum distance d ≥ |I|+1 = 8 [i]
