Linear OA(9105, 125, F9, 66) (dual of [125, 20, 67]-code), using construction XX applied to C1 = C([61,39]), C2 = C([0,49]), C3 = C1 + C2 = C([0,39]), and C∩ = C1 ∩ C2 = C([61,49]) based on
  1. linear OA(971, 80, F9, 59) (dual of [80, 9, 60]-code), using the primitive BCH-code C(I) with length 80 = 92−1, defining interval I = {−19,−18,…,39}, and designed minimum distance d ≥ |I|+1 = 60 [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]
