MinT - Best Known (237−121, 237, s)-Nets in Base 3

Best Known (237−121, 237, s)-Nets in Base 3

(237−121, 237, 74)-Net over F₃ — Constructive and digital

Digital (116, 237, 74)-net over F₃, using

t-expansion [i] based on digital (107, 237, 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]

(237−121, 237, 120)-Net over F₃ — Digital

Digital (116, 237, 120)-net over F₃, using

t-expansion [i] based on digital (113, 237, 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]

(237−121, 237, 815)-Net in Base 3 — Upper bound on s

There is no (116, 237, 816)-net in base 3, because

1 times m-reduction [i] would yield (116, 236, 816)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 42511 131230 996060 487489 165237 977757 439546 614818 856490 180529 553094 700338 927684 642408 471773 416518 526892 132036 518529 > 3²³⁶ [i]
