Linear OOA(3²⁴⁰, 4194396, F₃, 2, 21) (dual of [(4194396, 2), 8388552, 22]-NRT-code), using (u,Â u+v)-construction based on

linear OOA(3³⁰, 95, F₃, 2, 10) (dual of [(95, 2), 160, 11]-NRT-code), using
- embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3³⁰, 95, F₃, 10) (dual of [95, 65, 11]-code), using
  - discarding factors / shortening the dual code based on linear OA(3³⁰, 121, F₃, 10) (dual of [121, 91, 11]-code), using
    - the BCH-code C(I) with length 121Â | 3⁵âˆ’1, defining interval IÂ =Â {1,17,33,…,24}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 11 [i]
