MinT - Best Known (198−69, 198, s)-Nets in Base 3

Best Known (198−69, 198, s)-Nets in Base 3

(198−69, 198, 156)-Net over F₃ — Constructive and digital

Digital (129, 198, 156)-net over F₃, using

16 times m-reduction [i] based on digital (129, 214, 156)-net over F₃, using
- trace code for nets [i] based on digital (22, 107, 78)-net over F₉, using
  - net from sequence [i] based on digital (22, 77)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 22 and N(F) ≥ 78, using
      - F₃ from the tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(198−69, 198, 276)-Net over F₃ — Digital

Digital (129, 198, 276)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(198−69, 198, 3901)-Net in Base 3 — Upper bound on s

There is no (129, 198, 3902)-net in base 3, because

1 times m-reduction [i] would yield (129, 197, 3902)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 9872 054416 733206 951101 109624 517348 783848 901618 190214 523834 594320 269585 153514 698792 446446 684605 > 3¹⁹⁷ [i]
