Linear OOA(3¹⁸⁶, 1677760, F₃, 5, 17) (dual of [(1677760, 5), 8388614, 18]-NRT-code), using (u,Â u+v)-construction based on

linear OOA(3²⁰, 40, F₃, 5, 8) (dual of [(40, 5), 180, 9]-NRT-code), using
- extracting embedded OOA [i] based on digital (12, 20, 40)-net over F₃, using
  - trace code for nets [i] based on digital (2, 10, 20)-net over F₉, using
    - net from sequence [i] based on digital (2, 19)-sequence over F₉, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 2 and N(F) ≥ 20, using
        a function field by GarcÃa and Quoos [i]
linear OOA(3¹⁶⁶, 1677720, F₃, 5, 17) (dual of [(1677720, 5), 8388434, 18]-NRT-code), using
