MinT - Best Known (195−105, 195, s)-Nets in Base 3

Best Known (195−105, 195, s)-Nets in Base 3

(195−105, 195, 64)-Net over F₃ — Constructive and digital

Digital (90, 195, 64)-net over F₃, using

t-expansion [i] based on digital (89, 195, 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]

(195−105, 195, 96)-Net over F₃ — Digital

Digital (90, 195, 96)-net over F₃, using

t-expansion [i] based on digital (89, 195, 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]

(195−105, 195, 559)-Net in Base 3 — Upper bound on s

There is no (90, 195, 560)-net in base 3, because

1 times m-reduction [i] would yield (90, 194, 560)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 376 204170 274236 817320 194351 235482 687618 464333 702566 630507 250660 609281 327392 835874 970354 531457 > 3¹⁹⁴ [i]
