Linear OOA(3¹³², 1684200, F₃, 5, 11) (dual of [(1684200, 5), 8420868, 12]-NRT-code), using (u,Â u+v)-construction based on

linear OOA(3²⁶, 6480, F₃, 5, 5) (dual of [(6480, 5), 32374, 6]-NRT-code), using
- OOA 2-folding and stacking with additional row [i] based on linear OA(3²⁶, 12961, F₃, 5) (dual of [12961, 12935, 6]-code), using
  - discarding factors / shortening the dual code 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
      - base reduction for projective spaces (embedding PG(6,81) in PG(12,9)) [i] based on linear OA(81⁷, 6481, F₈₁, 5) (dual of [6481, 6474, 6]-code), using
        a code by Danev and Olsson [i]
