Linear OOA(2²³⁰, 181, F₂, 2, 74) (dual of [(181, 2), 132, 75]-NRT-code), using 1 times NRT-code embedding in larger space based on linear OOA(2²²⁸, 180, F₂, 2, 74) (dual of [(180, 2), 132, 75]-NRT-code), using

strength reduction [i] based on linear OOA(2²²⁸, 180, F₂, 2, 75) (dual of [(180, 2), 132, 76]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(8⁴⁶, 45, F₈, 2, 37) (dual of [(45, 2), 44, 38]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,52P) [i] based on function field F/F₈ with g(F) = 9 and N(F) ≥ 45, using
      - an explicitly constructive algebraic function field [i]
  2. linear OA(2¹, 4, F₂, 1) (dual of [4, 3, 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]
