Linear OOA(4¹²⁴, 54300, F₄, 3, 19) (dual of [(54300, 3), 162776, 20]-NRT-code), using embedding of OOA with Gilbertâ€“VarÅ¡amov bound based on linear OA(4¹²⁴, 54300, F₄, 19) (dual of [54300, 54176, 20]-code), using

discarding factors / shortening the dual code based on linear OA(4¹²⁴, 65552, F₄, 19) (dual of [65552, 65428, 20]-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OA(4¹¹, 15, F₄, 9) (dual of [15, 4, 10]-code), using
    - 2 times truncation [i] based on linear OA(4¹³, 17, F₄, 11) (dual of [17, 4, 12]-code), using
      - projective code from ovoid in PG(3,Â 4) [i]
  2. linear OA(4¹¹³, 65537, F₄, 19) (dual of [65537, 65424, 20]-code), using
