Best Known (112, 247, s)-Nets in Base 3

(112, 247, 74)-Net over F₃ — Constructive and digital

Digital (112, 247, 74)-net over F₃, using

t-expansion [i] based on digital (107, 247, 74)-net over F₃, using
- net from sequence [i] based on digital (107, 73)-sequence over F₃, using
  - base reduction for sequences [i] based on digital (17, 73)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 17 and N(F) ≥ 74, using
      - a function field by GarcÃa and Quoos [i]

(112, 247, 104)-Net over F₃ — Digital

Digital (112, 247, 104)-net over F₃, using

t-expansion [i] based on digital (102, 247, 104)-net over F₃, using
- net from sequence [i] based on digital (102, 103)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 102 and N(F) ≥ 104, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(112, 247, 663)-Net in Base 3 — Upper bound on s

There is no (112, 247, 664)-net in base 3, because

1 times m-reduction [i] would yield (112, 246, 664)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2362 976825 557747 210229 809784 292145 451354 441212 321106 077154 101364 209679 422118 342856 000683 795369 330165 124041 341602 492897 > 3²⁴⁶ [i]
