Linear OOA(2¹⁶⁴, 40, F₂, 5, 64) (dual of [(40, 5), 36, 65]-NRT-code), using OOA 2-folding based on linear OOA(2¹⁶⁴, 80, F₂, 3, 64) (dual of [(80, 3), 76, 65]-NRT-code), using

1 step truncation [i] based on linear OOA(2¹⁶⁵, 81, F₂, 3, 65) (dual of [(81, 3), 78, 66]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4⁴², 27, F₄, 3, 32) (dual of [(27, 3), 39, 33]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,48P) [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]
