Linear OOA(2⁴⁸, 24, F₂, 3, 22) (dual of [(24, 3), 24, 23]-NRT-code), using strength reduction based on linear OOA(2⁴⁸, 24, F₂, 3, 23) (dual of [(24, 3), 24, 24]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4¹², 8, F₄, 3, 11) (dual of [(8, 3), 12, 12]-NRT-code), using
  - discarding factors / shortening the dual code based on linear OOA(4¹², 9, F₄, 3, 11) (dual of [(9, 3), 15, 12]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,15P) [i] based on function field F/F₄ with g(F) = 1 and N(F) ≥ 9, using
      - the Hermitian function field over F₄ [i]
2. linear OA(2¹, 3, F₂, 1) (dual of [3, 2, 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]
