Linear OOA(4²⁵⁸, 189, F₄, 2, 120) (dual of [(189, 2), 120, 121]-NRT-code), using strength reduction based on linear OOA(4²⁵⁸, 189, F₄, 2, 121) (dual of [(189, 2), 120, 122]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16⁶⁶, 63, F₁₆, 2, 60) (dual of [(63, 2), 60, 61]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(16⁶⁶, 64, F₁₆, 2, 60) (dual of [(64, 2), 62, 61]-NRT-code), using
    - algebraic-geometric NRT-code AG(2;F,67P) [i] based on function field F/F₁₆ with g(F) = 6 and N(F) ≥ 65, using
      - the Hermitian function field over F₁₆ [i]
2. linear OA(4¹, 3, F₄, 1) (dual of [3, 2, 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]
