Linear OA(4²⁵⁶, 343, F₄, 117) (dual of [343, 87, 118]-code), using 2 times truncation based on linear OA(4²⁵⁸, 345, F₄, 119) (dual of [345, 87, 120]-code), using

concatenation of two codes [i] based on
1. linear OA(64⁴⁰, 69, F₆₄, 39) (dual of [69, 29, 40]-code), using
  - discarding factors / shortening the dual code based on linear OA(64⁴⁰, 79, F₆₄, 39) (dual of [79, 39, 40]-code), using
    - algebraic-geometric code AG(F,39P) [i] based on function field F/F₆₄ with g(F) = 1 and N(F) ≥ 80, using
      - a function field by SÃ©mirat [i]
