MinT - Best Known (181−95, 181, s)-Nets in Base 3

Best Known (181−95, 181, s)-Nets in Base 3

(181−95, 181, 61)-Net over F₃ — Constructive and digital

Digital (86, 181, 61)-net over F₃, using

net from sequence [i] based on digital (86, 60)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 60)-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]

(181−95, 181, 84)-Net over F₃ — Digital

Digital (86, 181, 84)-net over F₃, using

t-expansion [i] based on digital (71, 181, 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]

(181−95, 181, 571)-Net in Base 3 — Upper bound on s

There is no (86, 181, 572)-net in base 3, because

1 times m-reduction [i] would yield (86, 180, 572)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 76 267601 304122 272294 737535 344220 819025 837528 156661 053315 515709 891587 294922 752739 938257 > 3¹⁸⁰ [i]
