Linear OA(9¹²⁵, 173, F₉, 68) (dual of [173, 48, 69]-code), using 1 times truncation based on linear OA(9¹²⁶, 174, F₉, 69) (dual of [174, 48, 70]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁴, 58, F₈₁, 34) (dual of [58, 24, 35]-code or 58-arc in PG(33,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³⁴, 81, F₈₁, 34) (dual of [81, 47, 35]-code or 81-arc in PG(33,81)), using
    - Reedâ€“Solomon code RS(47,81) [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]
