Linear OA(3¹⁰⁶, 139, F₃, 46) (dual of [139, 33, 47]-code), using 1 times truncation based on linear OA(3¹⁰⁷, 140, F₃, 47) (dual of [140, 33, 48]-code), using

concatenation of two codes [i] based on
1. linear OA(27²⁴, 35, F₂₇, 23) (dual of [35, 11, 24]-code), using
  - discarding factors / shortening the dual code based on linear OA(27²⁴, 38, F₂₇, 23) (dual of [38, 14, 24]-code), using
    - extended algebraic-geometric code AG_e(F,14P) [i] based on function field F/F₂₇ with g(F) = 1 and N(F) ≥ 38, using
      - a function field by SÃ©mirat [i]
2. linear OA(3¹, 4, F₃, 1) (dual of [4, 3, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
