Linear OA(3¹²¹, 187, F₃, 46) (dual of [187, 66, 47]-code), using 1 times truncation based on linear OA(3¹²², 188, F₃, 47) (dual of [188, 66, 48]-code), using

concatenation of two codes [i] based on
1. linear OA(27²⁵, 47, F₂₇, 23) (dual of [47, 22, 24]-code), using
  - discarding factors / shortening the dual code based on linear OA(27²⁵, 48, F₂₇, 23) (dual of [48, 23, 24]-code), using
    - extended algebraic-geometric code AG_e(F,24P) [i] based on function field F/F₂₇ with g(F) = 2 and N(F) ≥ 48, using
      - a function field by GarcÃa and Quoos [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]
