Linear OA(9⁹⁴, 140, F₉, 48) (dual of [140, 46, 49]-code), using 1 times truncation based on linear OA(9⁹⁵, 141, F₉, 49) (dual of [141, 46, 50]-code), using

concatenation of two codes [i] based on
1. linear OA(81²⁴, 47, F₈₁, 24) (dual of [47, 23, 25]-code or 47-arc in PG(23,81)), using
  - discarding factors / shortening the dual code based on linear OA(81²⁴, 81, F₈₁, 24) (dual of [81, 57, 25]-code or 81-arc in PG(23,81)), using
    - Reedâ€“Solomon code RS(57,81) [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]
