Linear OA(3¹⁹¹, 399, F₃, 56) (dual of [399, 208, 57]-code), using 1 times truncation based on linear OA(3¹⁹², 400, F₃, 57) (dual of [400, 208, 58]-code), using

concatenation of two codes [i] based on
1. linear OA(81²⁸, 80, F₈₁, 28) (dual of [80, 52, 29]-code or 80-arc in PG(27,81)), using
  - discarding factors / shortening the dual code based on linear OA(81²⁸, 81, F₈₁, 28) (dual of [81, 53, 29]-code or 81-arc in PG(27,81)), using
    - Reedâ€“Solomon code RS(53,81) [i]
2. linear OA(3¹, 5, F₃, 1) (dual of [5, 4, 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]
