Information on Result #671741

Linear OA(25668, 66821, F256, 24) (dual of [66821, 66753, 25]-code), using (u, u+v)-construction based on
  1. linear OA(25621, 1285, F256, 12) (dual of [1285, 1264, 13]-code), using
    • the BCH-code C(I) with length 1285 | 2562−1, defining interval I = {1,155,309,…,410}, and designed minimum distance d ≥ |I|+1 = 13 [i]
  2. linear OA(25647, 65536, F256, 24) (dual of [65536, 65489, 25]-code), using
    • an extension Ce(23) of the primitive narrow-sense BCH-code C(I) with length 65535 = 2562−1, defining interval I = [1,23], and designed minimum distance d ≥ |I|+1 = 24 [i]
