Linear OA(9¹³⁸, 170, F₉, 82) (dual of [170, 32, 83]-code), using 1 times truncation based on linear OA(9¹³⁹, 171, F₉, 83) (dual of [171, 32, 84]-code), using

concatenation of two codes [i] based on
1. linear OA(81⁴¹, 57, F₈₁, 41) (dual of [57, 16, 42]-code or 57-arc in PG(40,81)), using
  - discarding factors / shortening the dual code based on linear OA(81⁴¹, 81, F₈₁, 41) (dual of [81, 40, 42]-code or 81-arc in PG(40,81)), using
    - Reedâ€“Solomon code RS(40,81) [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]
