Information on Result #669879

Linear OA(6474, 262339, F64, 20) (dual of [262339, 262265, 21]-code), using (u, u+v)-construction based on
  1. linear OA(6416, 195, F64, 10) (dual of [195, 179, 11]-code), using
    • the BCH-code C(I) with length 195 | 642−1, defining interval I = {1,8,15,…,64}, and designed minimum distance d ≥ |I|+1 = 11 [i]
  2. linear OA(6458, 262144, F64, 20) (dual of [262144, 262086, 21]-code), using
    • an extension Ce(19) of the primitive narrow-sense BCH-code C(I) with length 262143 = 643−1, defining interval I = [1,19], and designed minimum distance d ≥ |I|+1 = 20 [i]
