Linear OOA(9²⁰, 19443, F₉, 2, 5) (dual of [(19443, 2), 38866, 6]-NRT-code), using generalized (u,Â u+v)-construction based on

linear OOA(9¹, 6481, F₉, 2, 1) (dual of [(6481, 2), 12961, 2]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(9¹, s, F₉, 2, 1) for arbitrarily large s, using
  - appending 1 arbitrary column [i] based on linear OA(9¹, s, F₉, 1) (dual of [s, s−1, 2]-code) for arbitrarily large s, using
    - parity-check code [i]
linear OOA(9⁵, 6481, F₉, 2, 2) (dual of [(6481, 2), 12957, 3]-NRT-code), using
- discarding factors / shortening the dual code based on linear OOA(9⁵, 7381, F₉, 2, 2) (dual of [(7381, 2), 14757, 3]-NRT-code), using
