Linear OA(999, 118, F9, 63) (dual of [118, 19, 64]-code), using construction XX applied to C1 = C([61,40]), C2 = C([0,49]), C3 = C1 + C2 = C([0,40]), and C∩ = C1 ∩ C2 = C([61,49]) based on
  1. linear OA(972, 80, F9, 60) (dual of [80, 8, 61]-code), using the primitive BCH-code C(I) with length 80 = 92−1, defining interval I = {−19,−18,…,40}, and designed minimum distance d ≥ |I|+1 = 61 [i]
  2. linear OA(965, 80, F9, 50) (dual of [80, 15, 51]-code), using the primitive expurgated narrow-sense BCH-code C(I) with length 80 = 92−1, defining interval I = [0,49], and designed minimum distance d ≥ |I|+1 = 51 [i]
