Linear OOA(4²⁰⁴, 174, F₄, 2, 73) (dual of [(174, 2), 144, 74]-NRT-code), using OOA 2-folding based on linear OA(4²⁰⁴, 348, F₄, 73) (dual of [348, 144, 74]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁹, 87, F₆₄, 36) (dual of [87, 48, 37]-code), using
  - discarding factors / shortening the dual code based on linear OA(64³⁹, 103, F₆₄, 36) (dual of [103, 64, 37]-code), using
    - algebraic-geometric code AG(F,66P) [i] based on function field F/F₆₄ with g(F) = 3 and N(F) ≥ 104, using
      - a function field by SÃ©mirat [i]
2. linear OA(4¹, 4, F₄, 1) (dual of [4, 3, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(4¹, s, F₄, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
