Linear OOA(2⁴⁰, 27, F₂, 2, 20) (dual of [(27, 2), 14, 21]-NRT-code), using strength reduction based on linear OOA(2⁴⁰, 27, F₂, 2, 21) (dual of [(27, 2), 14, 22]-NRT-code), using

concatenation of two NRT-codes [i] based on
1. linear OOA(4¹¹, 9, F₄, 2, 10) (dual of [(9, 2), 7, 11]-NRT-code), using
  - extended algebraic-geometric NRT-code AG_e(2;F,7P) [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]
