Digital (133, 152, 532749)-net over F₄, using embedding of OOA with Gilbertâ€“VarÅ¡amov bound based on linear OA(4¹⁵², 532749, F₄, 19) (dual of [532749, 532597, 20]-code), using

discarding factors / shortening the dual code based on linear OA(4¹⁵², 1048592, F₄, 19) (dual of [1048592, 1048440, 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(4¹⁴¹, 1048577, F₄, 19) (dual of [1048577, 1048436, 20]-code), using
