MinT - Best Known (142−115, 142, s)-Nets in Base 9

Best Known (142−115, 142, s)-Nets in Base 9

(142−115, 142, 78)-Net over F₉ — Constructive and digital

Digital (27, 142, 78)-net over F₉, using

t-expansion [i] based on digital (22, 142, 78)-net over F₉, using
- net from sequence [i] based on digital (22, 77)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 22 and N(F) ≥ 78, using
    - F₃ from the tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(142−115, 142, 110)-Net over F₉ — Digital

Digital (27, 142, 110)-net over F₉, using

t-expansion [i] based on digital (26, 142, 110)-net over F₉, using
- net from sequence [i] based on digital (26, 109)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 26 and N(F) ≥ 110, using
    - a curve from the manYPoints database [i]

(142−115, 142, 598)-Net in Base 9 — Upper bound on s

There is no (27, 142, 599)-net in base 9, because

1 times m-reduction [i] would yield (27, 141, 599)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 372 094494 174999 893509 987617 379981 601009 424240 629839 632327 180484 665553 232182 330566 022654 557477 266887 970714 346196 304236 131959 840379 557625 > 9¹⁴¹ [i]
