Linear OA(9¹³⁹, 185, F₉, 78) (dual of [185, 46, 79]-code), using 1 times truncation based on linear OA(9¹⁴⁰, 186, F₉, 79) (dual of [186, 46, 80]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁹, 62, F₈₁, 39) (dual of [62, 23, 40]-code or 62-arc in PG(38,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³⁹, 81, F₈₁, 39) (dual of [81, 42, 40]-code or 81-arc in PG(38,81)), using
    - Reedâ€“Solomon code RS(42,81) [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]
