Linear OOA(2²⁵³, 204, F₂, 2, 78) (dual of [(204, 2), 155, 79]-NRT-code), using 1 step truncation based on linear OOA(2²⁵⁴, 205, F₂, 2, 79) (dual of [(205, 2), 156, 80]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(16⁴³, 41, F₁₆, 2, 39) (dual of [(41, 2), 39, 40]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(16⁴³, 45, F₁₆, 2, 39) (dual of [(45, 2), 47, 40]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,50P) [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
      - a function field by GarcÃa and Quoos [i]
2. linear OA(2¹, 5, F₂, 1) (dual of [5, 4, 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]
