Linear OOA(2¹⁴⁹, 59, F₂, 3, 76) (dual of [(59, 3), 28, 77]-NRT-code), using 1 step truncation based on linear OOA(2¹⁵⁰, 60, F₂, 3, 77) (dual of [(60, 3), 30, 78]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4⁴⁵, 20, F₄, 3, 38) (dual of [(20, 3), 15, 39]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(4⁴⁵, 21, F₄, 3, 38) (dual of [(21, 3), 18, 39]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,24P) [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, 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]
