Linear OOA(4²⁰⁵, 105, F₄, 2, 163) (dual of [(105, 2), 5, 164]-NRT-code), using strength reduction based on linear OOA(4²⁰⁵, 105, F₄, 2, 165) (dual of [(105, 2), 5, 166]-NRT-code), using

juxtaposition [i] based on
1. linear OOA(4²⁵, 15, F₄, 2, 21) (dual of [(15, 2), 5, 22]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,8P) [i] based on function field F/F₄ with g(F) = 4 and N(F) ≥ 15, using
    - an explicitly constructive algebraic function field [i]
2. linear OOA(4¹⁷⁵, 90, F₄, 2, 143) (dual of [(90, 2), 5, 144]-NRT-code), using
  - 4¹ times duplication [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
      1. 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]
      2. linear OOA(4⁸, 5, F₄, 2, 8) (dual of [(5, 2), 2, 9]-NRT-code), using
        extended Reedâ€“Solomon NRT-code RS_e(2;2,4) [i]
