(29, 48, 7283)-net in base 128, using base change based on digital (23, 42, 7283)-net over F₂₅₆, using

256² times duplication [i] based on digital (21, 40, 7283)-net over F₂₅₆, using
- net defined by OOA [i] based on linear OOA(256⁴⁰, 7283, F₂₅₆, 19, 19) (dual of [(7283, 19), 138337, 20]-NRT-code), using
  - OOA 9-folding and stacking with additional row [i] based on linear OA(256⁴⁰, 65548, F₂₅₆, 19) (dual of [65548, 65508, 20]-code), using
    - constructionÂ X applied to C([0,9]) âŠ‚ C([0,7]) [i] based on
      1. linear OA(256³⁷, 65537, F₂₅₆, 19) (dual of [65537, 65500, 20]-code), using the expurgated narrow-sense BCH-code C(I) with length 65537Â | 256⁴âˆ’1, defining interval IÂ =Â [0,9], and minimum distance dÂ â‰¥ |{−9,−8,…,9}|+1Â =Â 20 (BCH-bound) [i]
