Linear OA(27110, 186, F27, 68) (dual of [186, 76, 69]-code), using construction XX applied to C1 = C([181,65]), C2 = C([0,66]), C3 = C1 + C2 = C([0,65]), and C∩ = C1 ∩ C2 = C([181,66]) based on
  1. linear OA(27108, 182, F27, 67) (dual of [182, 74, 68]-code), using the BCH-code C(I) with length 182 | 272−1, defining interval I = {−1,0,…,65}, and designed minimum distance d ≥ |I|+1 = 68 [i]
  2. linear OA(27108, 182, F27, 67) (dual of [182, 74, 68]-code), using the expurgated narrow-sense BCH-code C(I) with length 182 | 272−1, defining interval I = [0,66], and designed minimum distance d ≥ |I|+1 = 68 [i]
