Linear OA(4²⁰⁹, 395, F₄, 68) (dual of [395, 186, 69]-code), using 1 times truncation based on linear OA(4²¹⁰, 396, F₄, 69) (dual of [396, 186, 70]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁷, 99, F₆₄, 34) (dual of [99, 62, 35]-code), using
  - discarding factors / shortening the dual code based on linear OA(64³⁷, 103, F₆₄, 34) (dual of [103, 66, 35]-code), using
    - algebraic-geometric code AG(F,68P) [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
