Linear OOA(128⁷⁵, large, F₁₂₈, 2, 12), using 128¹ times duplication based on linear OOA(128⁷⁴, large, F₁₂₈, 2, 12), using

4 times NRT-code embedding in larger space [i] based on linear OOA(128⁶⁶, 8388602, F₁₂₈, 2, 12) (dual of [(8388602, 2), 16777138, 13]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(128²¹, 4194301, F₁₂₈, 2, 6) (dual of [(4194301, 2), 8388581, 7]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(128²¹, 8388602, F₁₂₈, 6) (dual of [8388602, 8388581, 7]-code), using
      - discarding factors / shortening the dual code based on linear OA(128²¹, large, F₁₂₈, 6) (dual of [large, large−21, 7]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 17895697Â | 128⁴âˆ’1, defining interval IÂ =Â [0,5], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 7 [i]
