Linear OA(3²⁴¹, 409, F₃, 80) (dual of [409, 168, 81]-code), using 1 times truncation based on linear OA(3²⁴², 410, F₃, 81) (dual of [410, 168, 82]-code), using

concatenation of two codes [i] based on
1. linear OA(81⁴⁰, 82, F₈₁, 40) (dual of [82, 42, 41]-code or 82-arc in PG(39,81)), using
  - extended Reedâ€“Solomon code RS_e(42,81) [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]
