Linear OA(1642, 259, F16, 23) (dual of [259, 217, 24]-code), using construction XX applied to C1 = C([254,20]), C2 = C([0,21]), C3 = C1 + C2 = C([0,20]), and C∩ = C1 ∩ C2 = C([254,21]) based on
  1. linear OA(1640, 255, F16, 22) (dual of [255, 215, 23]-code), using the primitive BCH-code C(I) with length 255 = 162−1, defining interval I = {−1,0,…,20}, and designed minimum distance d ≥ |I|+1 = 23 [i]
  2. linear OA(1640, 255, F16, 22) (dual of [255, 215, 23]-code), using the primitive expurgated narrow-sense BCH-code C(I) with length 255 = 162−1, defining interval I = [0,21], and designed minimum distance d ≥ |I|+1 = 23 [i]
