Linear OA(4²⁵⁵, 273, F₄, 161) (dual of [273, 18, 162]-code), using 2 times truncation based on linear OA(4²⁵⁷, 275, F₄, 163) (dual of [275, 18, 164]-code), using

concatenation of two codes [i] based on
1. linear OA(16⁴⁶, 55, F₁₆, 40) (dual of [55, 9, 41]-code), using
  - discarding factors / shortening the dual code based on linear OA(16⁴⁶, 64, F₁₆, 40) (dual of [64, 18, 41]-code), using
    - algebraic-geometric code AG(F,23P) [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(4³, 5, F₄, 3) (dual of [5, 2, 4]-code or 5-arc in PG(2,4) or 5-cap in PG(2,4)), using
