(28, 48, 6554)-net in base 128, using t-expansion based on (27, 48, 6554)-net in base 128, using

base change [i] based on digital (21, 42, 6554)-net over F₂₅₆, using
- net defined by OOA [i] based on linear OOA(256⁴², 6554, F₂₅₆, 21, 21) (dual of [(6554, 21), 137592, 22]-NRT-code), using
  - OOA 10-folding and stacking with additional row [i] based on linear OA(256⁴², 65541, F₂₅₆, 21) (dual of [65541, 65499, 22]-code), using
    - discarding factors / shortening the dual code based on linear OA(256⁴², 65542, F₂₅₆, 21) (dual of [65542, 65500, 22]-code), using
      - constructionÂ X applied to C([0,10]) âŠ‚ C([0,9]) [i] based on
        linear OA(256⁴¹, 65537, F₂₅₆, 21) (dual of [65537, 65496, 22]-code), using the expurgated narrow-sense BCH-code C(I) with length 65537Â | 256⁴âˆ’1, defining interval IÂ =Â [0,10], and minimum distance dÂ â‰¥ |{−10,−9,…,10}|+1Â =Â 22 (BCH-bound) [i]
