Digital (198, 218, 4141523)-net over F₃, using embedding of OOA with Gilbertâ€“VarÅ¡amov bound based on linear OOA(3²¹⁸, 4141523, F₃, 2, 20) (dual of [(4141523, 2), 8282828, 21]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(3²¹⁸, 4194333, F₃, 2, 20) (dual of [(4194333, 2), 8388448, 21]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(3²², 32, F₃, 2, 10) (dual of [(32, 2), 42, 11]-NRT-code), using
    - extracting embedded OOA [i] based on digital (12, 22, 32)-net over F₃, using
      - trace code for nets [i] based on digital (1, 11, 16)-net over F₉, using
        net from sequence [i] based on digital (1, 15)-sequence over F₉, using
        Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 1 and N(F) ≥ 16, using
        a function field by GarcÃa and Quoos [i]
  2. linear OOA(3¹⁹⁶, 4194301, F₃, 2, 20) (dual of [(4194301, 2), 8388406, 21]-NRT-code), using
    - OOA 2-folding [i] based on linear OA(3¹⁹⁶, 8388602, F₃, 20) (dual of [8388602, 8388406, 21]-code), using
      - discarding factors / shortening the dual code based on linear OA(3¹⁹⁶, large, F₃, 20) (dual of [large, large−196, 21]-code), using
