MinT - Best Known (246−133, 246, s)-Nets in Base 3

Best Known (246−133, 246, s)-Nets in Base 3

(246−133, 246, 74)-Net over F₃ — Constructive and digital

Digital (113, 246, 74)-net over F₃, using

t-expansion [i] based on digital (107, 246, 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]

(246−133, 246, 120)-Net over F₃ — Digital

Digital (113, 246, 120)-net over F₃, using

net from sequence [i] based on digital (113, 119)-sequence over F₃, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 113 and N(F) ≥ 120, using
  - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(246−133, 246, 686)-Net in Base 3 — Upper bound on s

There is no (113, 246, 687)-net in base 3, because

1 times m-reduction [i] would yield (113, 245, 687)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 784 850827 859174 842232 545688 278971 599616 171760 080258 487477 013414 826481 312180 139776 704673 382406 155731 184441 967918 360285 > 3²⁴⁵ [i]
