Linear OA(9¹³¹, 203, F₉, 64) (dual of [203, 72, 65]-code), using 1 times truncation based on linear OA(9¹³², 204, F₉, 65) (dual of [204, 72, 66]-code), using

concatenation of two codes [i] based on
1. linear OA(81³², 68, F₈₁, 32) (dual of [68, 36, 33]-code or 68-arc in PG(31,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³², 81, F₈₁, 32) (dual of [81, 49, 33]-code or 81-arc in PG(31,81)), using
    - Reedâ€“Solomon code RS(49,81) [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]
