(43, 68, 5504)-net in base 128, using net defined by OOA based on OOA(128⁶⁸, 5504, S₁₂₈, 28, 25), using

OOA 3-folding and stacking with additional row [i] based on OOA(128⁶⁸, 16513, S₁₂₈, 4, 25), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(128¹², 129, F₁₂₈, 4, 12) (dual of [(129, 4), 504, 13]-NRT-code), using
    - extended Reedâ€“Solomon NRT-code RS_e(4;504,128) [i]
  2. OOA(128⁵⁶, 16384, S₁₂₈, 4, 25), using
    - OOA 4-folding [i] based on OA(128⁵⁶, 65536, S₁₂₈, 25), using
      - discarding factors based on OA(128⁵⁶, 65538, S₁₂₈, 25), using
        discarding parts of the base [i] based on linear OA(256⁴⁹, 65538, F₂₅₆, 25) (dual of [65538, 65489, 26]-code), using
        constructionÂ X applied to C_e(24) âŠ‚ C_e(23) [i] based on
        linear OA(256⁴⁹, 65536, F₂₅₆, 25) (dual of [65536, 65487, 26]-code), using an extension C_e(24) of the primitive narrow-sense BCH-code C(I) with length 65535Â = 256²âˆ’1, defining interval IÂ =Â [1,24], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 25 [i]
        linear OA(256⁴⁷, 65536, F₂₅₆, 24) (dual of [65536, 65489, 25]-code), using an extension C_e(23) of the primitive narrow-sense BCH-code C(I) with length 65535Â = 256²âˆ’1, defining interval IÂ =Â [1,23], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 24 [i]
        linear OA(256⁰, 2, F₂₅₆, 0) (dual of [2, 2, 1]-code), using
        discarding factors / shortening the dual code based on linear OA(256⁰, s, F₂₅₆, 0) (dual of [s, s, 1]-code) for arbitrarily large s, using
        OA with only one run / dual of code without redundancy [i]
