Linear OOA(3²⁰⁵, 4194369, F₃, 2, 18) (dual of [(4194369, 2), 8388533, 19]-NRT-code), using (u,Â u+v)-construction based on

linear OOA(3²⁵, 68, F₃, 2, 9) (dual of [(68, 2), 111, 10]-NRT-code), using
- embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3²⁵, 68, F₃, 9) (dual of [68, 43, 10]-code), using
  - discarding factors / shortening the dual code based on linear OA(3²⁵, 80, F₃, 9) (dual of [80, 55, 10]-code), using
    - the primitive cyclic code C(A) with length 80Â = 3⁴âˆ’1, defining set AÂ =Â {0,1,2,4,5,7,53}, and minimum distance dÂ â‰¥ |{−1,0,…,7}|+1Â =Â 10 (BCH-bound) [i]
