Linear OOA(2²⁵⁷, 155, F₂, 3, 76) (dual of [(155, 3), 208, 77]-NRT-code), using 1 step truncation based on linear OOA(2²⁵⁸, 156, F₂, 3, 77) (dual of [(156, 3), 210, 78]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8⁴⁷, 39, F₈, 3, 38) (dual of [(39, 3), 70, 39]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8⁴⁷, 45, F₈, 3, 38) (dual of [(45, 3), 88, 39]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,96P) [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]
