Linear OA(9¹⁰⁴, 146, F₉, 56) (dual of [146, 42, 57]-code), using 1 times truncation based on linear OA(9¹⁰⁵, 147, F₉, 57) (dual of [147, 42, 58]-code), using

concatenation of two codes [i] based on
1. linear OA(81²⁸, 49, F₈₁, 28) (dual of [49, 21, 29]-code or 49-arc in PG(27,81)), using
  - discarding factors / shortening the dual code based on linear OA(81²⁸, 81, F₈₁, 28) (dual of [81, 53, 29]-code or 81-arc in PG(27,81)), using
    - Reedâ€“Solomon code RS(53,81) [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]
