Linear OOA(2¹⁷⁷, 66, F₂, 4, 60) (dual of [(66, 4), 87, 61]-NRT-code), using OOA 2-folding based on linear OOA(2¹⁷⁷, 132, F₂, 2, 60) (dual of [(132, 2), 87, 61]-NRT-code), using

strength reduction [i] based on linear OOA(2¹⁷⁷, 132, F₂, 2, 61) (dual of [(132, 2), 87, 62]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(8³⁷, 33, F₈, 2, 30) (dual of [(33, 2), 29, 31]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(8³⁷, 34, F₈, 2, 30) (dual of [(34, 2), 31, 31]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(2;F,37P) [i] based on function field F/F₈ with g(F) = 7 and N(F) ≥ 34, using
        a function field by SÃ©mirat [i]
  2. linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 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]
