Linear OA(826, 67, F8, 15) (dual of [67, 41, 16]-code), using construction XX applied to C1 = C([62,12]), C2 = C([0,13]), C3 = C1 + C2 = C([0,12]), and C∩ = C1 ∩ C2 = C([62,13]) based on
  1. linear OA(824, 63, F8, 14) (dual of [63, 39, 15]-code), using the primitive BCH-code C(I) with length 63 = 82−1, defining interval I = {−1,0,…,12}, and designed minimum distance d ≥ |I|+1 = 15 [i]
  2. linear OA(824, 63, F8, 14) (dual of [63, 39, 15]-code), using the primitive expurgated narrow-sense BCH-code C(I) with length 63 = 82−1, defining interval I = [0,13], and designed minimum distance d ≥ |I|+1 = 15 [i]
