Linear OA(9¹¹¹, 155, F₉, 60) (dual of [155, 44, 61]-code), using 1 times truncation based on linear OA(9¹¹², 156, F₉, 61) (dual of [156, 44, 62]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁰, 52, F₈₁, 30) (dual of [52, 22, 31]-code or 52-arc in PG(29,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³⁰, 81, F₈₁, 30) (dual of [81, 51, 31]-code or 81-arc in PG(29,81)), using
    - Reedâ€“Solomon code RS(51,81) [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]
