Linear OA(986, 105, F9, 55) (dual of [105, 19, 56]-code), using construction XX applied to C([0,30]) ⊂ C([0,22]) ⊂ C([0,21]) based on
  1. linear OA(973, 82, F9, 61) (dual of [82, 9, 62]-code), using the expurgated narrow-sense BCH-code C(I) with length 82 | 94−1, defining interval I = [0,30], and minimum distance d ≥ |{−30,−29,…,30}|+1 = 62 (BCH-bound) [i]
  2. linear OA(965, 82, F9, 45) (dual of [82, 17, 46]-code), using the expurgated narrow-sense BCH-code C(I) with length 82 | 94−1, defining interval I = [0,22], and minimum distance d ≥ |{−22,−21,…,22}|+1 = 46 (BCH-bound) [i]
