Linear OA(993, 742, F9, 34) (dual of [742, 649, 35]-code), using construction XX applied to C1 = C([726,29]), C2 = C([0,31]), C3 = C1 + C2 = C([0,29]), and C∩ = C1 ∩ C2 = C([726,31]) based on
  1. linear OA(985, 728, F9, 32) (dual of [728, 643, 33]-code), using the primitive BCH-code C(I) with length 728 = 93−1, defining interval I = {−2,−1,…,29}, and designed minimum distance d ≥ |I|+1 = 33 [i]
  2. linear OA(985, 728, F9, 32) (dual of [728, 643, 33]-code), using the primitive expurgated narrow-sense BCH-code C(I) with length 728 = 93−1, defining interval I = [0,31], and designed minimum distance d ≥ |I|+1 = 33 [i]
