Linear OOA(4²⁴⁷, 699069, F₄, 27, 25) (dual of [(699069, 27), 18874616, 26]-NRT-code), using OOA 4-folding and stacking with additional row based on linear OOA(4²⁴⁷, 2796277, F₄, 3, 25) (dual of [(2796277, 3), 8388584, 26]-NRT-code), using

(u,Â u+v)-construction [i] based on
1. linear OOA(4³⁰, 76, F₄, 3, 12) (dual of [(76, 3), 198, 13]-NRT-code), using
  - extracting embedded OOA [i] based on digital (18, 30, 76)-net over F₄, using
    - trace code for nets [i] based on digital (3, 15, 38)-net over F₁₆, using
      - net from sequence [i] based on digital (3, 37)-sequence over F₁₆, using
        Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 3 and N(F) ≥ 38, using
        a function field by SÃ©mirat [i]
