Linear OA(4²⁵¹, 338, F₄, 114) (dual of [338, 87, 115]-code), using 2 times truncation based on linear OA(4²⁵³, 340, F₄, 116) (dual of [340, 87, 117]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁹, 68, F₆₄, 38) (dual of [68, 29, 39]-code), using
  - discarding factors / shortening the dual code based on linear OA(64³⁹, 79, F₆₄, 38) (dual of [79, 40, 39]-code), using
    - algebraic-geometric code AG(F,40P) [i] based on function field F/F₆₄ with g(F) = 1 and N(F) ≥ 80, using
      - a function field by SÃ©mirat [i]
