linear OOA(7¹¹, 21, F₇, 3, 7) (dual of [(21, 3), 52, 8]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(7³, 8, F₇, 3, 3) (dual of [(8, 3), 21, 4]-NRT-code), using
    - extended Reedâ€“Solomon NRT-code RS_e(3;21,7) [i]
  2. linear OOA(7⁸, 13, F₇, 3, 7) (dual of [(13, 3), 31, 8]-NRT-code), using
    - extracting embedded OOA [i] based on digital (1, 8, 13)-net over F₇, using
      - 5 times m-reduction [i] based on digital (1, 13, 13)-net over F₇, using
        a shift-net [i]
linear OOA(7⁹⁷, 1921600, F₇, 3, 15) (dual of [(1921600, 3), 5764703, 16]-NRT-code), using
- OOA 3-folding [i] based on linear OA(7⁹⁷, 5764800, F₇, 15) (dual of [5764800, 5764703, 16]-code), using
