Linear OOA(2¹⁸⁰, 40, F₂, 6, 80) (dual of [(40, 6), 60, 81]-NRT-code), using OOA 2-folding based on linear OOA(2¹⁸⁰, 80, F₂, 3, 80) (dual of [(80, 3), 60, 81]-NRT-code), using

1 step truncation [i] based on linear OOA(2¹⁸¹, 81, F₂, 3, 81) (dual of [(81, 3), 62, 82]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4⁵⁰, 27, F₄, 3, 40) (dual of [(27, 3), 31, 41]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,40P) [i] based on function field F/F₄ with g(F) = 10 and N(F) ≥ 27, using
      - an explicitly constructive algebraic function field [i]
  2. linear OA(2¹, 3, F₂, 1) (dual of [3, 2, 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]
