MinT - Best Known (245−149, 245, s)-Nets in Base 3

Best Known (245−149, 245, s)-Nets in Base 3

(245−149, 245, 64)-Net over F₃ — Constructive and digital

Digital (96, 245, 64)-net over F₃, using

t-expansion [i] based on digital (89, 245, 64)-net over F₃, using
- net from sequence [i] based on digital (89, 63)-sequence over F₃, using
  - base reduction for sequences [i] based on digital (13, 63)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 13 and N(F) ≥ 64, using
      - a function field by GarcÃa and Quoos [i]

(245−149, 245, 96)-Net over F₃ — Digital

Digital (96, 245, 96)-net over F₃, using

t-expansion [i] based on digital (89, 245, 96)-net over F₃, using
- net from sequence [i] based on digital (89, 95)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 89 and N(F) ≥ 96, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(245−149, 245, 461)-Net in Base 3 — Upper bound on s

There is no (96, 245, 462)-net in base 3, because

1 times m-reduction [i] would yield (96, 244, 462)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 280 362389 244107 711350 876388 740911 340286 422378 910087 227411 361630 666703 302468 323747 710248 054686 776136 433503 652735 128941 > 3²⁴⁴ [i]
