Linear OOA(2⁶³, 41, F₂, 2, 30) (dual of [(41, 2), 19, 31]-NRT-code), using 1 step truncation based on linear OOA(2⁶⁴, 42, F₂, 2, 31) (dual of [(42, 2), 20, 32]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4¹⁸, 14, F₄, 2, 15) (dual of [(14, 2), 10, 16]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,12P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, 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]
