Linear OOA(9¹¹⁰, 70, F₉, 2, 64) (dual of [(70, 2), 30, 65]-NRT-code), using OOA 2-folding based on linear OA(9¹¹⁰, 140, F₉, 64) (dual of [140, 30, 65]-code), using

1 times truncation [i] based on linear OA(9¹¹¹, 141, F₉, 65) (dual of [141, 30, 66]-code), using
- concatenation of two codes [i] based on
  1. linear OA(81³², 47, F₈₁, 32) (dual of [47, 15, 33]-code or 47-arc in PG(31,81)), using
    - discarding factors / shortening the dual code based on linear OA(81³², 81, F₈₁, 32) (dual of [81, 49, 33]-code or 81-arc in PG(31,81)), using
      - Reedâ€“Solomon code RS(49,81) [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]
