Linear OOA(2¹⁴¹, 80, F₂, 3, 48) (dual of [(80, 3), 99, 49]-NRT-code), using strength reduction based on linear OOA(2¹⁴¹, 80, F₂, 3, 49) (dual of [(80, 3), 99, 50]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(8²⁷, 20, F₈, 3, 24) (dual of [(20, 3), 33, 25]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(8²⁷, 24, F₈, 3, 24) (dual of [(24, 3), 45, 25]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,47P) [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]
