Linear OA(12834, 392, F128, 19) (dual of [392, 358, 20]-code), using construction XX applied to C1 = C([2,18]), C2 = C([0,15]), C3 = C1 + C2 = C([2,15]), and C∩ = C1 ∩ C2 = C([0,18]) based on
  1. linear OA(12828, 381, F128, 17) (dual of [381, 353, 18]-code), using the BCH-code C(I) with length 381 | 1282−1, defining interval I = {2,3,…,18}, and designed minimum distance d ≥ |I|+1 = 18 [i]
  2. linear OA(12826, 381, F128, 16) (dual of [381, 355, 17]-code), using the expurgated narrow-sense BCH-code C(I) with length 381 | 1282−1, defining interval I = [0,15], and designed minimum distance d ≥ |I|+1 = 17 [i]
