1 times truncation [i] based on linear OA(3¹⁸⁵, 272, F₃, 69) (dual of [272, 87, 70]-code), using
- concatenation of two codes [i] based on
  1. linear OA(27³⁹, 68, F₂₇, 34) (dual of [68, 29, 35]-code), using
    - extended algebraic-geometric code AG_e(F,33P) [i] based on function field F/F₂₇ with g(F) = 5 and N(F) ≥ 68, using
      - a function field by SÃ©mirat [i]
