Linear OA(12849, 392, F128, 28) (dual of [392, 343, 29]-code), using construction XX applied to C1 = C([2,27]), C2 = C([0,24]), C3 = C1 + C2 = C([2,24]), and C∩ = C1 ∩ C2 = C([0,27]) based on
  1. linear OA(12843, 381, F128, 26) (dual of [381, 338, 27]-code), using the BCH-code C(I) with length 381 | 1282−1, defining interval I = {2,3,…,27}, and designed minimum distance d ≥ |I|+1 = 27 [i]
  2. linear OA(12841, 381, F128, 25) (dual of [381, 340, 26]-code), using the expurgated narrow-sense BCH-code C(I) with length 381 | 1282−1, defining interval I = [0,24], and designed minimum distance d ≥ |I|+1 = 26 [i]
