Linear OA(858, 90, F8, 31) (dual of [90, 32, 32]-code), using construction XX applied to C1 = C([54,19]), C2 = C([0,21]), C3 = C1 + C2 = C([0,19]), and C∩ = C1 ∩ C2 = C([54,21]) based on
  1. linear OA(842, 63, F8, 29) (dual of [63, 21, 30]-code), using the primitive BCH-code C(I) with length 63 = 82−1, defining interval I = {−9,−8,…,19}, and designed minimum distance d ≥ |I|+1 = 30 [i]
  2. linear OA(835, 63, F8, 22) (dual of [63, 28, 23]-code), using the primitive expurgated narrow-sense BCH-code C(I) with length 63 = 82−1, defining interval I = [0,21], and designed minimum distance d ≥ |I|+1 = 23 [i]
