Linear OA(4²⁰⁹, 383, F₄, 70) (dual of [383, 174, 71]-code), using 1 times truncation based on linear OA(4²¹⁰, 384, F₄, 71) (dual of [384, 174, 72]-code), using

concatenation of two codes [i] based on
1. linear OA(64³⁸, 96, F₆₄, 35) (dual of [96, 58, 36]-code), using
  - discarding factors / shortening the dual code based on linear OA(64³⁸, 103, F₆₄, 35) (dual of [103, 65, 36]-code), using
    - algebraic-geometric code AG(F,67P) [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
  - 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]
