Linear OOA(2¹⁶⁸, 87, F₂, 4, 44) (dual of [(87, 4), 180, 45]-NRT-code), using OOA 2-folding based on linear OOA(2¹⁶⁸, 174, F₂, 2, 44) (dual of [(174, 2), 180, 45]-NRT-code), using

strength reduction [i] based on linear OOA(2¹⁶⁸, 174, F₂, 2, 45) (dual of [(174, 2), 180, 46]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(32²², 29, F₃₂, 2, 22) (dual of [(29, 2), 36, 23]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(32²², 32, F₃₂, 2, 22) (dual of [(32, 2), 42, 23]-NRT-code), using
      - Reedâ€“Solomon NRT-code RS(2;42,32) [i]
  2. linear OA(2¹, 6, F₂, 1) (dual of [6, 5, 2]-code), using
    - discarding factors / shortening the dual code based on linear OA(2¹, s, F₂, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
      - parity-check code [i]
