Linear OOA(2578, 381, F25, 2, 31) (dual of [(381, 2), 684, 32]-NRT-code), using (u, u+v)-construction based on
  1. linear OOA(2519, 66, F25, 2, 15) (dual of [(66, 2), 113, 16]-NRT-code), using
  2. linear OOA(2559, 315, F25, 2, 31) (dual of [(315, 2), 571, 32]-NRT-code), using
    • OOA 2-folding [i] based on linear OA(2559, 630, F25, 31) (dual of [630, 571, 32]-code), using
      • construction X applied to Ce(30) ⊂ Ce(28) [i] based on
        1. linear OA(2558, 625, F25, 31) (dual of [625, 567, 32]-code), using an extension Ce(30) of the primitive narrow-sense BCH-code C(I) with length 624 = 252−1, defining interval I = [1,30], and designed minimum distance d ≥ |I|+1 = 31 [i]
