Best Known (12, 12+21, s)-Nets in Base 9

(12, 12+21, 40)-Net over F₉ — Constructive and digital

Digital (12, 33, 40)-net over F₉, using

t-expansion [i] based on digital (8, 33, 40)-net over F₉, using
- net from sequence [i] based on digital (8, 39)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 8 and N(F) ≥ 40, using
    - a function field by SÃ©mirat [i]

(12, 12+21, 56)-Net over F₉ — Digital

Digital (12, 33, 56)-net over F₉, using

net from sequence [i] based on digital (12, 55)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 12 and N(F) ≥ 56, using
  - a curve from the manYPoints database [i]

(12, 12+21, 634)-Net in Base 9 — Upper bound on s

There is no (12, 33, 635)-net in base 9, because

1 times m-reduction [i] would yield (12, 32, 635)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3 450744 092512 717604 659035 170545 > 9³² [i]
