Linear OOA(128⁶¹, large, F₁₂₈, 3, 8), using 128² times duplication based on linear OOA(128⁵⁹, large, F₁₂₈, 3, 8), using

strength reduction [i] based on linear OOA(128⁵⁹, large, F₁₂₈, 3, 9), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(128¹³, 4194301, F₁₂₈, 3, 4) (dual of [(4194301, 3), 12582890, 5]-NRT-code), using
    - OA 2-folding and stacking [i] based on linear OA(128¹³, 8388602, F₁₂₈, 4) (dual of [8388602, 8388589, 5]-code), using
      - discarding factors / shortening the dual code based on linear OA(128¹³, large, F₁₂₈, 4) (dual of [large, large−13, 5]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 17895697Â | 128⁴âˆ’1, defining interval IÂ =Â [0,3], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 5 [i]
  2. linear OOA(128⁴⁶, 5592402, F₁₂₈, 3, 9) (dual of [(5592402, 3), 16777160, 10]-NRT-code), using
    - (u,Â u+v)-construction [i] based on
      1. linear OOA(128¹³, 4194301, F₁₂₈, 3, 4) (dual of [(4194301, 3), 12582890, 5]-NRT-code) (see above)
      2. linear OOA(128³³, 2796201, F₁₂₈, 3, 9) (dual of [(2796201, 3), 8388570, 10]-NRT-code), using
        OOA 3-folding [i] based on linear OA(128³³, large, F₁₂₈, 9) (dual of [large, large−33, 10]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 15790321Â | 128⁸âˆ’1, defining interval IÂ =Â [0,4], and minimum distance dÂ â‰¥ |{−4,−3,…,4}|+1Â =Â 10 (BCH-bound) [i]
