Best Known (109−14, 109, s)-Nets in Base 9

(109−14, 109, 2396742)-Net over F₉ — Constructive and digital

Digital (95, 109, 2396742)-net over F₉, using

9³ times duplication [i] based on digital (92, 106, 2396742)-net over F₉, using
- trace code for nets [i] based on digital (39, 53, 1198371)-net over F₈₁, using
  - net defined by OOA [i] based on linear OOA(81⁵³, 1198371, F₈₁, 14, 14) (dual of [(1198371, 14), 16777141, 15]-NRT-code), using
    - OA 7-folding and stacking [i] based on linear OA(81⁵³, 8388597, F₈₁, 14) (dual of [8388597, 8388544, 15]-code), using
      - discarding factors / shortening the dual code based on linear OA(81⁵³, large, F₈₁, 14) (dual of [large, large−53, 15]-code), using
        the expurgated narrow-sense BCH-code C(I) with length 21523360Â | 81⁴âˆ’1, defining interval IÂ =Â [0,13], and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 15 [i]

(109−14, 109, large)-Net over F₉ — Digital

Digital (95, 109, large)-net over F₉, using

2 times m-reduction [i] based on digital (95, 111, large)-net over F₉, using
- Gilbertâ€“VarÅ¡amov bound [i]

(109−14, 109, large)-Net in Base 9 — Upper bound on s

There is no (95, 109, large)-net in base 9, because

12 times m-reduction [i] would yield (95, 97, large)-net in base 9, but
- mutually orthogonal hypercube bound [i]
