Linear OA(8175, 531769, F81, 20) (dual of [531769, 531694, 21]-code), using (u, u+v)-construction based on
  1. linear OA(8117, 328, F81, 10) (dual of [328, 311, 11]-code), using
    • the BCH-code C(I) with length 328 | 812−1, defining interval I = {81,114,147,…,50}, and designed minimum distance d ≥ |I|+1 = 11 [i]
  2. linear OA(8158, 531441, F81, 20) (dual of [531441, 531383, 21]-code), using
    • an extension Ce(19) of the primitive narrow-sense BCH-code C(I) with length 531440 = 813−1, defining interval I = [1,19], and designed minimum distance d ≥ |I|+1 = 20 [i]
