Linear OA(9¹⁰⁹, 143, F₉, 62) (dual of [143, 34, 63]-code), using 1 times truncation based on linear OA(9¹¹⁰, 144, F₉, 63) (dual of [144, 34, 64]-code), using

concatenation of two codes [i] based on
1. linear OA(81³¹, 48, F₈₁, 31) (dual of [48, 17, 32]-code or 48-arc in PG(30,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³¹, 81, F₈₁, 31) (dual of [81, 50, 32]-code or 81-arc in PG(30,81)), using
    - Reedâ€“Solomon code RS(50,81) [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]
