strength reduction [i] based on linear OOA(3²⁴⁶, 81, F₃, 4, 131) (dual of [(81, 4), 78, 132]-NRT-code), using
- generalized (u,Â u+v)-construction [i] based on
  1. linear OOA(3⁵⁸, 27, F₃, 4, 43) (dual of [(27, 4), 50, 44]-NRT-code), using
    - discarding factors / shortening the dual code based on linear OOA(3⁵⁸, 28, F₃, 4, 43) (dual of [(28, 4), 54, 44]-NRT-code), using
      - extended algebraic-geometric NRT-code AG_e(4;F,68P) [i] based on function field F/F₃ with g(F) = 15 and N(F) ≥ 28, using
        an explicitly constructive algebraic function field [i]
