Linear OOA(3¹⁴⁶, 157, F₃, 2, 42) (dual of [(157, 2), 168, 43]-NRT-code), using OOA 2-folding based on linear OA(3¹⁴⁶, 314, F₃, 42) (dual of [314, 168, 43]-code), using

1 times truncation [i] based on linear OA(3¹⁴⁷, 315, F₃, 43) (dual of [315, 168, 44]-code), using
- concatenation of two codes [i] based on
  1. linear OA(81²¹, 63, F₈₁, 21) (dual of [63, 42, 22]-code or 63-arc in PG(20,81)), using
    - discarding factors / shortening the dual code based on linear OA(81²¹, 81, F₈₁, 21) (dual of [81, 60, 22]-code or 81-arc in PG(20,81)), using
      - Reedâ€“Solomon code RS(60,81) [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]
