Linear OOA(4¹⁶⁹, 932071, F₄, 21, 18) (dual of [(932071, 21), 19573322, 19]-NRT-code), using OOA 3-folding and stacking with additional row based on linear OOA(4¹⁶⁹, 2796214, F₄, 3, 18) (dual of [(2796214, 3), 8388473, 19]-NRT-code), using

discarding factors / shortening the dual code based on linear OOA(4¹⁶⁹, 2796215, F₄, 3, 18) (dual of [(2796215, 3), 8388476, 19]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(4¹², 14, F₄, 3, 9) (dual of [(14, 3), 30, 10]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,32P) [i] based on function field F/F₄ with g(F) = 3 and N(F) ≥ 14, using
      - an explicitly constructive algebraic function field [i]
  2. linear OOA(4¹⁵⁷, 2796201, F₄, 3, 18) (dual of [(2796201, 3), 8388446, 19]-NRT-code), using
    - OOA 3-folding [i] based on linear OA(4¹⁵⁷, large, F₄, 18) (dual of [large, large−157, 19]-code), using
      - the primitive expurgated narrow-sense BCH-code C(I) with length 16777215Â = 4¹²âˆ’1, defining interval IÂ =Â [0,17], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 19 [i]
