Linear OOA(9¹²³, 85, F₉, 2, 67) (dual of [(85, 2), 47, 68]-NRT-code), using OOA 2-folding based on linear OA(9¹²³, 170, F₉, 67) (dual of [170, 47, 68]-code), using

discarding factors / shortening the dual code based on linear OA(9¹²³, 171, F₉, 67) (dual of [171, 48, 68]-code), using
- concatenation of two codes [i] based on
  1. linear OA(81³³, 57, F₈₁, 33) (dual of [57, 24, 34]-code or 57-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]
