MinT - Best Known (130−91, 130, s)-Nets in Base 9

Best Known (130−91, 130, s)-Nets in Base 9

(130−91, 130, 81)-Net over F₉ — Constructive and digital

Digital (39, 130, 81)-net over F₉, using

t-expansion [i] based on digital (32, 130, 81)-net over F₉, using
- net from sequence [i] based on digital (32, 80)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 32 and N(F) ≥ 81, using
    - F₄ from the tower of function fields by Bezerra and GarcÃa over F₉ [i]

(130−91, 130, 140)-Net over F₉ — Digital

Digital (39, 130, 140)-net over F₉, using

net from sequence [i] based on digital (39, 139)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 39 and N(F) ≥ 140, using
  - a curve from the manYPoints database [i]

(130−91, 130, 1170)-Net in Base 9 — Upper bound on s

There is no (39, 130, 1171)-net in base 9, because

1 times m-reduction [i] would yield (39, 129, 1171)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 1255 953548 717143 339634 348839 589605 665457 727366 946065 854300 545221 602742 732638 695844 182986 916815 215158 292217 617400 477469 329337 > 9¹²⁹ [i]
