(46, 76, 4370)-net in base 128, using t-expansion based on (45, 76, 4370)-net in base 128, using

net defined by OOA [i] based on OOA(128⁷⁶, 4370, S₁₂₈, 31, 31), using
- OOA 15-folding and stacking with additional row [i] based on OA(128⁷⁶, 65551, S₁₂₈, 31), using
  - discarding factors based on OA(128⁷⁶, 65554, S₁₂₈, 31), using
    - discarding parts of the base [i] based on linear OA(256⁶⁶, 65554, F₂₅₆, 31) (dual of [65554, 65488, 32]-code), using
      - constructionÂ X applied to C([0,15]) âŠ‚ C([0,12]) [i] based on
        linear OA(256⁶¹, 65537, F₂₅₆, 31) (dual of [65537, 65476, 32]-code), using the expurgated narrow-sense BCH-code C(I) with length 65537Â | 256⁴âˆ’1, defining interval IÂ =Â [0,15], and minimum distance dÂ â‰¥ |{−15,−14,…,15}|+1Â =Â 32 (BCH-bound) [i]
