Linear OOA(2554, 381, F25, 2, 20) (dual of [(381, 2), 708, 21]-NRT-code), using (u, u+v)-construction based on
  1. linear OOA(2514, 66, F25, 2, 10) (dual of [(66, 2), 118, 11]-NRT-code), using
  2. linear OOA(2540, 315, F25, 2, 20) (dual of [(315, 2), 590, 21]-NRT-code), using
    • OOA 2-folding [i] based on linear OA(2540, 630, F25, 20) (dual of [630, 590, 21]-code), using
      • construction X applied to Ce(19) ⊂ Ce(17) [i] based on
        1. linear OA(2539, 625, F25, 20) (dual of [625, 586, 21]-code), using an extension Ce(19) of the primitive narrow-sense BCH-code C(I) with length 624 = 252−1, defining interval I = [1,19], and designed minimum distance d ≥ |I|+1 = 20 [i]
