Linear OA(9¹³⁵, 209, F₉, 66) (dual of [209, 74, 67]-code), using 1 times truncation based on linear OA(9¹³⁶, 210, F₉, 67) (dual of [210, 74, 68]-code), using

concatenation of two codes [i] based on
1. linear OA(81³³, 70, F₈₁, 33) (dual of [70, 37, 34]-code or 70-arc in PG(32,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³³, 81, F₈₁, 33) (dual of [81, 48, 34]-code or 81-arc in PG(32,81)), using
    - Reedâ€“Solomon code RS(48,81) [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]
