Linear OA(2569, 390713, F25, 15) (dual of [390713, 390644, 16]-code), using (u, u+v)-construction based on
  1. linear OA(2511, 78, F25, 7) (dual of [78, 67, 8]-code), using
    • the BCH-code C(I) with length 78 | 252−1, defining interval I = {1,18,35,…,25}, and designed minimum distance d ≥ |I|+1 = 8 [i]
  2. linear OA(2558, 390635, F25, 15) (dual of [390635, 390577, 16]-code), using
    • construction X applied to C([0,7]) ⊂ C([0,6]) [i] based on
