Linear OOA(4¹⁸⁵, 932073, F₄, 21, 19) (dual of [(932073, 21), 19573348, 20]-NRT-code), using OOA 3-folding and stacking with additional row based on linear OOA(4¹⁸⁵, 2796220, F₄, 3, 19) (dual of [(2796220, 3), 8388475, 20]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(4¹⁸⁵, 2796222, F₄, 3, 19) (dual of [(2796222, 3), 8388481, 20]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(4¹⁶, 21, F₄, 3, 9) (dual of [(21, 3), 47, 10]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,53P) [i] based on function field F/F₄ with g(F) = 7 and N(F) ≥ 21, using
      - an explicitly constructive algebraic function field [i]
