Linear OOA(3¹⁹², 2097221, F₃, 5, 17) (dual of [(2097221, 5), 10485913, 18]-NRT-code), using OOA 2-folding based on linear OOA(3¹⁹², 4194442, F₃, 3, 17) (dual of [(4194442, 3), 12583134, 18]-NRT-code), using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(3¹⁹², 4194442, F₃, 2, 17) (dual of [(4194442, 2), 8388692, 18]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(3²⁶, 141, F₃, 2, 8) (dual of [(141, 2), 256, 9]-NRT-code), using
    - embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(3²⁶, 141, F₃, 8) (dual of [141, 115, 9]-code), using
      - discarding factors / shortening the dual code based on linear OA(3²⁶, 242, F₃, 8) (dual of [242, 216, 9]-code), using
        the primitive expurgated narrow-sense BCH-code C(I) with length 242Â = 3⁵âˆ’1, defining interval IÂ =Â [0,7], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 9 [i]
