Best Known (39, 39+67, s)-Nets in Base 9

(39, 39+67, 81)-Net over F₉ — Constructive and digital

Digital (39, 106, 81)-net over F₉, using

t-expansion [i] based on digital (32, 106, 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]

(39, 39+67, 140)-Net over F₉ — Digital

Digital (39, 106, 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]

(39, 39+67, 1768)-Net in Base 9 — Upper bound on s

There is no (39, 106, 1769)-net in base 9, because

1 times m-reduction [i] would yield (39, 105, 1769)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 15845 042224 947114 547093 793139 912433 011219 458810 137583 350693 538039 599041 694149 900516 918557 926387 168329 > 9¹⁰⁵ [i]
