Linear OOA(2²⁵⁰, 171, F₂, 2, 92) (dual of [(171, 2), 92, 93]-NRT-code), using 1 step truncation based on linear OOA(2²⁵¹, 172, F₂, 2, 93) (dual of [(172, 2), 93, 94]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁵⁵, 43, F₈, 2, 46) (dual of [(43, 2), 31, 47]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁵⁵, 45, F₈, 2, 46) (dual of [(45, 2), 35, 47]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,43P) [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]
