Linear OOA(2¹³⁴, 40, F₂, 4, 61) (dual of [(40, 4), 26, 62]-NRT-code), using OOA 2-folding based on linear OOA(2¹³⁴, 80, F₂, 2, 61) (dual of [(80, 2), 26, 62]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(2¹³⁴, 81, F₂, 2, 61) (dual of [(81, 2), 28, 62]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4⁴⁰, 27, F₄, 2, 30) (dual of [(27, 2), 14, 31]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,23P) [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]
