Linear OA(9135, 142, F9, 71) (dual of [142, 7, 72]-code), using construction X applied to C([0,51]) ⊂ C([1,51]) based on
  1. linear OA(9116, 122, F9, 71) (dual of [122, 6, 72]-code), using the expurgated narrow-sense BCH-code C(I) with length 122 | 95−1, defining interval I = [0,51], and minimum distance d ≥ |{−19,−18,…,51}|+1 = 72 (BCH-bound) [i]
  2. linear OA(9115, 122, F9, 51) (dual of [122, 7, 52]-code), using the narrow-sense BCH-code C(I) with length 122 | 95−1, defining interval I = [1,51], and designed minimum distance d ≥ |I|+1 = 52 [i]
