Linear OOA(25106, 381, F25, 2, 42) (dual of [(381, 2), 656, 43]-NRT-code), using (u, u+v)-construction based on
  1. linear OOA(2525, 66, F25, 2, 21) (dual of [(66, 2), 107, 22]-NRT-code), using
  2. linear OOA(2581, 315, F25, 2, 42) (dual of [(315, 2), 549, 43]-NRT-code), using
    • OOA 2-folding [i] based on linear OA(2581, 630, F25, 42) (dual of [630, 549, 43]-code), using
      • construction X applied to Ce(41) ⊂ Ce(39) [i] based on
        1. linear OA(2580, 625, F25, 42) (dual of [625, 545, 43]-code), using an extension Ce(41) of the primitive narrow-sense BCH-code C(I) with length 624 = 252−1, defining interval I = [1,41], and designed minimum distance d ≥ |I|+1 = 42 [i]
