Linear OOA(3²¹¹, 4194456, F₃, 2, 19) (dual of [(4194456, 2), 8388701, 20]-NRT-code), using (u,Â u+v)-construction based on

linear OOA(3³⁰, 155, F₃, 2, 9) (dual of [(155, 2), 280, 10]-NRT-code), using
- embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3³⁰, 155, F₃, 9) (dual of [155, 125, 10]-code), using
  - discarding factors / shortening the dual code based on linear OA(3³⁰, 242, F₃, 9) (dual of [242, 212, 10]-code), using
    - the primitive narrow-sense BCH-code C(I) with length 242Â = 3⁵âˆ’1, defining interval IÂ =Â [1,9], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 10 [i]
