Linear OOA(2¹⁷⁰, 40, F₂, 5, 70) (dual of [(40, 5), 30, 71]-NRT-code), using OOA 2-folding based on linear OOA(2¹⁷⁰, 80, F₂, 3, 70) (dual of [(80, 3), 70, 71]-NRT-code), using

1 step truncation [i] based on linear OOA(2¹⁷¹, 81, F₂, 3, 71) (dual of [(81, 3), 72, 72]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4⁴⁵, 27, F₄, 3, 35) (dual of [(27, 3), 36, 36]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,45P) [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]
