strength reduction [i] based on linear OOA(2⁶⁷, 27, F₂, 3, 39) (dual of [(27, 3), 14, 40]-NRT-code), using
- concatenation of two NRT-codes [i] based on
  1. linear OOA(4²⁰, 9, F₄, 3, 19) (dual of [(9, 3), 7, 20]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;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]
