Best Known (40, 40+97, s)-Nets in Base 9

(40, 40+97, 81)-Net over F₉ — Constructive and digital

Digital (40, 137, 81)-net over F₉, using

t-expansion [i] based on digital (32, 137, 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]

(40, 40+97, 140)-Net over F₉ — Digital

Digital (40, 137, 140)-net over F₉, using

t-expansion [i] based on digital (39, 137, 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]

(40, 40+97, 1154)-Net in Base 9 — Upper bound on s

There is no (40, 137, 1155)-net in base 9, because

1 times m-reduction [i] would yield (40, 136, 1155)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 6030 418627 767321 799897 472651 910045 941318 681041 503803 449452 222176 139023 871945 039371 102572 868549 198762 507483 480835 727793 914817 077377 > 9¹³⁶ [i]
