Linear OA(2555, 15711, F25, 15) (dual of [15711, 15656, 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(2544, 15633, F25, 15) (dual of [15633, 15589, 16]-code), using
    • construction X applied to C([0,7]) ⊂ C([0,6]) [i] based on
      1. linear OA(2543, 15626, F25, 15) (dual of [15626, 15583, 16]-code), using the expurgated narrow-sense BCH-code C(I) with length 15626 | 256−1, defining interval I = [0,7], and minimum distance d ≥ |{−7,−6,…,7}|+1 = 16 (BCH-bound) [i]
      2. linear OA(2537, 15626, F25, 13) (dual of [15626, 15589, 14]-code), using the expurgated narrow-sense BCH-code C(I) with length 15626 | 256−1, defining interval I = [0,6], and minimum distance d ≥ |{−6,−5,…,6}|+1 = 14 (BCH-bound) [i]
