Linear OOA(4¹³³, 40241, F₄, 2, 21) (dual of [(40241, 2), 80349, 22]-NRT-code), using embedding of OOA with Gilbertâ€“VarÅ¡amov bound based on linear OA(4¹³³, 40241, F₄, 21) (dual of [40241, 40108, 22]-code), using

discarding factors / shortening the dual code based on linear OA(4¹³³, 65552, F₄, 21) (dual of [65552, 65419, 22]-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OA(4¹², 16, F₄, 10) (dual of [16, 4, 11]-code), using
    - 1 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(4¹²¹, 65536, F₄, 21) (dual of [65536, 65415, 22]-code), using
    - an extension C_e(20) of the primitive narrow-sense BCH-code C(I) with length 65535Â = 4⁸âˆ’1, defining interval IÂ =Â [1,20], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 21 [i]
