MinT - Best Known (250−153, 250, s)-Nets in Base 3

Best Known (250−153, 250, s)-Nets in Base 3

(250−153, 250, 64)-Net over F₃ — Constructive and digital

Digital (97, 250, 64)-net over F₃, using

t-expansion [i] based on digital (89, 250, 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]

(250−153, 250, 96)-Net over F₃ — Digital

Digital (97, 250, 96)-net over F₃, using

t-expansion [i] based on digital (89, 250, 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]

(250−153, 250, 461)-Net in Base 3 — Upper bound on s

There is no (97, 250, 462)-net in base 3, because

1 times m-reduction [i] would yield (97, 249, 462)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 71916 936290 403529 305646 012935 856355 527510 375561 516775 565248 858139 112638 541762 570536 284192 731627 199953 574427 649309 064025 > 3²⁴⁹ [i]
