  1. linear OOA(6410, 80, F64, 2, 9) (dual of [(80, 2), 150, 10]-NRT-code), using
  2. linear OOA(6438, 2051, F64, 2, 19) (dual of [(2051, 2), 4064, 20]-NRT-code), using
    • OOA 2-folding [i] based on linear OA(6438, 4102, F64, 19) (dual of [4102, 4064, 20]-code), using
      • construction X applied to C([0,9]) ⊂ C([0,8]) [i] based on
        1. linear OA(6437, 4097, F64, 19) (dual of [4097, 4060, 20]-code), using the expurgated narrow-sense BCH-code C(I) with length 4097 | 644−1, defining interval I = [0,9], and minimum distance d ≥ |{−9,−8,…,9}|+1 = 20 (BCH-bound) [i]
