MinT - Best Known (187−103, 187, s)-Nets in Base 3

Best Known (187−103, 187, s)-Nets in Base 3

(187−103, 187, 59)-Net over F₃ — Constructive and digital

Digital (84, 187, 59)-net over F₃, using

net from sequence [i] based on digital (84, 58)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 58)-sequence over F₉, using
  - s-reduction 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]

(187−103, 187, 84)-Net over F₃ — Digital

Digital (84, 187, 84)-net over F₃, using

t-expansion [i] based on digital (71, 187, 84)-net over F₃, using
- net from sequence [i] based on digital (71, 83)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 71 and N(F) ≥ 84, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(187−103, 187, 497)-Net in Base 3 — Upper bound on s

There is no (84, 187, 498)-net in base 3, because

1 times m-reduction [i] would yield (84, 186, 498)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 60953 270205 409668 246679 854908 474803 532440 745645 077240 929271 698542 054598 777701 133023 573937 > 3¹⁸⁶ [i]
