Linear OOA(3¹⁴⁹, 172, F₃, 2, 41) (dual of [(172, 2), 195, 42]-NRT-code), using OOA 2-folding based on linear OA(3¹⁴⁹, 344, F₃, 41) (dual of [344, 195, 42]-code), using

discarding factors / shortening the dual code based on linear OA(3¹⁴⁹, 345, F₃, 41) (dual of [345, 196, 42]-code), using
- concatenation of two codes [i] based on
  1. linear OA(81²⁰, 69, F₈₁, 20) (dual of [69, 49, 21]-code or 69-arc in PG(19,81)), using
    - discarding factors / shortening the dual code based on linear OA(81²⁰, 81, F₈₁, 20) (dual of [81, 61, 21]-code or 81-arc in PG(19,81)), using
      - Reedâ€“Solomon code RS(61,81) [i]
  2. linear OA(3¹, 5, F₃, 1) (dual of [5, 4, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(3¹, s, F₃, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
