Best Known (43, 43+47, s)-Nets in Base 3

(43, 43+47, 42)-Net over F₃ — Constructive and digital

Digital (43, 90, 42)-net over F₃, using

t-expansion [i] based on digital (39, 90, 42)-net over F₃, using
- net from sequence [i] based on digital (39, 41)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 39 and N(F) ≥ 42, using
    - an explicitly constructive algebraic function field [i]

(43, 43+47, 56)-Net over F₃ — Digital

Digital (43, 90, 56)-net over F₃, using

t-expansion [i] based on digital (40, 90, 56)-net over F₃, using
- net from sequence [i] based on digital (40, 55)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 40 and N(F) ≥ 56, using
    - a curve from the manYPoints database [i]

(43, 43+47, 309)-Net in Base 3 — Upper bound on s

There is no (43, 90, 310)-net in base 3, because

1 times m-reduction [i] would yield (43, 89, 310)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3 118174 093950 191526 687077 416918 085547 158457 > 3⁸⁹ [i]
