Linear OOA(3¹⁸¹, 142, F₃, 2, 63) (dual of [(142, 2), 103, 64]-NRT-code), using OOA 2-folding based on linear OA(3¹⁸¹, 284, F₃, 63) (dual of [284, 103, 64]-code), using

discarding factors / shortening the dual code based on linear OA(3¹⁸¹, 285, F₃, 63) (dual of [285, 104, 64]-code), using
- concatenation of two codes [i] based on
  1. linear OA(81³¹, 57, F₈₁, 31) (dual of [57, 26, 32]-code or 57-arc in PG(30,81)), using
    - discarding factors / shortening the dual code based on linear OA(81³¹, 81, F₈₁, 31) (dual of [81, 50, 32]-code or 81-arc in PG(30,81)), using
      - Reedâ€“Solomon code RS(50,81) [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]
