Linear OOA(3²²³, 2562000, F₃, 5, 22) (dual of [(2562000, 5), 12809777, 23]-NRT-code), using embedding of OOA with Gilbertâ€“VarÅ¡amov bound based on linear OOA(3²²³, 2562000, F₃, 3, 22) (dual of [(2562000, 3), 7685777, 23]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(3²²³, 2796208, F₃, 3, 22) (dual of [(2796208, 3), 8388401, 23]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(3¹², 7, F₃, 3, 11) (dual of [(7, 3), 9, 12]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,9P) [i] based on function field F/F₃ with g(F) = 1 and N(F) ≥ 7, using
      - an explicitly constructive algebraic function field [i]
