Digital (20, 28, 2129789)-net over F₂₅₆, using net defined by OOA based on linear OOA(256²⁸, 2129789, F₂₅₆, 12, 8) (dual of [(2129789, 12), 25557440, 9]-NRT-code), using

OOA stacking with additional row [i] based on linear OOA(256²⁸, 2129790, F₂₅₆, 4, 8) (dual of [(2129790, 4), 8519132, 9]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(256⁶, 32640, F₂₅₆, 4, 4) (dual of [(32640, 4), 130554, 5]-NRT-code), using
    - OA 2-folding and stacking [i] based on linear OA(256⁶, 65280, F₂₅₆, 4) (dual of [65280, 65274, 5]-code), using
      - 1 times truncation [i] based on linear OA(256⁷, 65281, F₂₅₆, 5) (dual of [65281, 65274, 6]-code), using
        a code by Danev and Olsson [i]
  2. linear OOA(256²², 2097150, F₂₅₆, 4, 8) (dual of [(2097150, 4), 8388578, 9]-NRT-code), using
    - OOA 4-folding [i] based on linear OA(256²², 8388600, F₂₅₆, 8) (dual of [8388600, 8388578, 9]-code), using
      - discarding factors / shortening the dual code based on linear OA(256²², large, F₂₅₆, 8) (dual of [large, large−22, 9]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 256³âˆ’1, defining interval IÂ =Â [0,7], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 9 [i]
