Best Known (38, 38+105, s)-Nets in Base 9

(38, 38+105, 81)-Net over F₉ — Constructive and digital

Digital (38, 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]

(38, 38+105, 128)-Net over F₉ — Digital

Digital (38, 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]

(38, 38+105, 988)-Net in Base 9 — Upper bound on s

There is no (38, 143, 989)-net in base 9, because

1 times m-reduction [i] would yield (38, 142, 989)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 3288 270084 121214 449095 595051 754453 336812 473649 804674 885692 958679 733088 995356 092477 254996 673177 876432 328598 557756 189503 014783 923799 267745 > 9¹⁴² [i]
