Linear OA(9¹⁵⁰, 228, F₉, 74) (dual of [228, 78, 75]-code), using strength reduction based on linear OA(9¹⁵⁰, 228, F₉, 75) (dual of [228, 78, 76]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁷, 76, F₈₁, 37) (dual of [76, 39, 38]-code or 76-arc in PG(36,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³⁷, 81, F₈₁, 37) (dual of [81, 44, 38]-code or 81-arc in PG(36,81)), using
    - Reedâ€“Solomon code RS(44,81) [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]
