linear OOA(4⁵, 5, F₄, 2, 5) (dual of [(5, 2), 5, 6]-NRT-code), using
- extended Reedâ€“Solomon NRT-code RS_e(2;5,4) [i]
linear OOA(4²²⁹, 117, F₄, 2, 183) (dual of [(117, 2), 5, 184]-NRT-code), using
- strength reduction [i] based on linear OOA(4²²⁹, 117, F₄, 2, 184) (dual of [(117, 2), 5, 185]-NRT-code), using
  - juxtaposition [i] based on
    1. linear OOA(4²³, 14, F₄, 2, 20) (dual of [(14, 2), 5, 21]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,7P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, using
        an explicitly constructive algebraic function field [i]

        linear OOA(4²³, 14, F₄, 2, 20) (dual of [(14, 2), 5, 21]-NRT-code) (see above)
        linear OOA(4¹⁷³, 89, F₄, 2, 142) (dual of [(89, 2), 5, 143]-NRT-code), using
        1 step truncation [i] based on linear OOA(4¹⁷⁴, 90, F₄, 2, 143) (dual of [(90, 2), 6, 144]-NRT-code), using
        concatenation of two NRT-codes [i] based on
        linear OA(16¹⁵, 18, F₁₆, 15) (dual of [18, 3, 16]-code or 18-arc in PG(14,16)), using
        Denniston code D(1,16) [i]
