OOA(128⁴⁰, 2113470, S₁₂₈, 4, 10), using OOA 2-folding based on OOA(128⁴⁰, 4226940, S₁₂₈, 2, 10), using

discarding factors based on OOA(128⁴⁰, 4226941, S₁₂₈, 2, 10), using
- (u,Â u+v)-construction [i] based on
  1. OOA(128⁸, 32640, S₁₂₈, 2, 5), using
    - OOA 2-folding [i] based on OA(128⁸, 65280, S₁₂₈, 5), using
      - discarding factors based on OA(128⁸, 65281, S₁₂₈, 5), using
        discarding parts of the base [i] based on linear OA(256⁷, 65281, F₂₅₆, 5) (dual of [65281, 65274, 6]-code), using
        a code by Danev and Olsson [i]
  2. OOA(128³², 4194301, S₁₂₈, 2, 10), using
    - OOA 2-folding [i] based on OA(128³², 8388602, S₁₂₈, 10), using
      - discarding factors based on OA(128³², large, S₁₂₈, 10), using
        discarding parts of the base [i] based on linear OA(256²⁸, large, F₂₅₆, 10) (dual of [large, large−28, 11]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 256³âˆ’1, defining interval IÂ =Â [0,9], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]
