Linear OA(4¹⁹¹, 16411, F₄, 33) (dual of [16411, 16220, 34]-code), using (u,Â u+v)-construction based on

linear OA(4²², 26, F₄, 16) (dual of [26, 4, 17]-code), using
- juxtaposition [i] based on
  1. linear OA(4⁵, 9, F₄, 4) (dual of [9, 4, 5]-code), using
    - discarding factors / shortening the dual code based on linear OA(4⁵, 11, F₄, 4) (dual of [11, 6, 5]-code), using
      - quaternary constacyclic codes with minimum distance 5 [i]
  2. linear OA(4¹³, 17, F₄, 11) (dual of [17, 4, 12]-code), using
    - projective code from ovoid in PG(3,Â 4) [i]
linear OA(4¹⁶⁹, 16385, F₄, 33) (dual of [16385, 16216, 34]-code), using
