Linear OA(9¹⁴⁷, 203, F₉, 80) (dual of [203, 56, 81]-code), using 1 times truncation based on linear OA(9¹⁴⁸, 204, F₉, 81) (dual of [204, 56, 82]-code), using

concatenation of two codes [i] based on
1. linear OA(81⁴⁰, 68, F₈₁, 40) (dual of [68, 28, 41]-code or 68-arc in PG(39,81)), using
  - discarding factors / shortening the dual code based on linear OA(81⁴⁰, 81, F₈₁, 40) (dual of [81, 41, 41]-code or 81-arc in PG(39,81)), using
    - Reedâ€“Solomon code RS(41,81) [i]
2. linear OA(9¹, 3, F₉, 1) (dual of [3, 2, 2]-code), using
  - discarding factors / shortening the dual code based on linear OA(9¹, s, F₉, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
