Linear OOA(3¹¹⁸, 1684201, F₃, 5, 10) (dual of [(1684201, 5), 8420887, 11]-NRT-code), using (u,Â u+v)-construction based on

linear OOA(3²⁷, 6481, F₃, 5, 5) (dual of [(6481, 5), 32378, 6]-NRT-code), using
- OOA 2-folding and stacking with additional row [i] based on linear OA(3²⁷, 12963, F₃, 5) (dual of [12963, 12936, 6]-code), using
  - 1 times code embedding in larger space [i] based on linear OA(3²⁶, 12962, F₃, 5) (dual of [12962, 12936, 6]-code), using
    - trace code [i] based on linear OA(9¹³, 6481, F₉, 5) (dual of [6481, 6468, 6]-code), using
