(66, 75, 4194651)-net in base 9, using (u,Â u+v)-construction based on

(5, 9, 351)-net in base 9, using
- base change [i] based on digital (2, 6, 351)-net over F₂₇, using
  - net defined by OOA [i] based on linear OOA(27⁶, 351, F₂₇, 4, 4) (dual of [(351, 4), 1398, 5]-NRT-code), using
    - OA 2-folding and stacking [i] based on linear OA(27⁶, 702, F₂₇, 4) (dual of [702, 696, 5]-code), using
      - 1 times truncation [i] based on linear OA(27⁷, 703, F₂₇, 5) (dual of [703, 696, 6]-code), using
        a code by Danev and Olsson [i]
digital (57, 66, 4194300)-net over F₉, using
