Linear OOA(2¹³⁸, 91, F₂, 2, 56) (dual of [(91, 2), 44, 57]-NRT-code), using 1 step truncation based on linear OOA(2¹³⁹, 92, F₂, 2, 57) (dual of [(92, 2), 45, 58]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8³¹, 23, F₈, 2, 28) (dual of [(23, 2), 15, 29]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8³¹, 24, F₈, 2, 28) (dual of [(24, 2), 17, 29]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,19P) [i] based on function field F/F₈ with g(F) = 3 and N(F) ≥ 24, using
      - the Klein quartic over F₈ [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]
