Best Known (48, 143, s)-Nets in Base 9

(48, 143, 81)-Net over F₉ — Constructive and digital

Digital (48, 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]

(48, 143, 163)-Net over F₉ — Digital

Digital (48, 143, 163)-net over F₉, using

net from sequence [i] based on digital (48, 162)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 48 and N(F) ≥ 163, using
  - Drinfeld modules of rank 1 [i]

(48, 143, 1725)-Net in Base 9 — Upper bound on s

There is no (48, 143, 1726)-net in base 9, because

1 times m-reduction [i] would yield (48, 142, 1726)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3239 855849 966837 923061 919525 955775 204681 512669 093116 285085 060071 612919 572880 299046 083459 511750 826715 740645 830431 794113 295970 465592 454481 > 9¹⁴² [i]
