MinT - Best Known (143−109, 143, s)-Nets in Base 9

Best Known (143−109, 143, s)-Nets in Base 9

(143−109, 143, 81)-Net over F₉ — Constructive and digital

Digital (34, 143, 81)-net over F₉, using

t-expansion [i] based on digital (32, 143, 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]

(143−109, 143, 128)-Net over F₉ — Digital

Digital (34, 143, 128)-net over F₉, using

t-expansion [i] based on digital (33, 143, 128)-net over F₉, using
- net from sequence [i] based on digital (33, 127)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 33 and N(F) ≥ 128, using
    - a curve from the manYPoints database [i]

(143−109, 143, 813)-Net in Base 9 — Upper bound on s

There is no (34, 143, 814)-net in base 9, because

1 times m-reduction [i] would yield (34, 142, 814)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3204 642382 291459 943559 900030 255753 976871 818547 577181 894952 472771 049613 334288 775464 128075 591252 351857 828886 127881 834913 867564 167161 406817 > 9¹⁴² [i]
