MinT - Best Known (189−87, 189, s)-Nets in Base 3

Best Known (189−87, 189, s)-Nets in Base 3

(189−87, 189, 75)-Net over F₃ — Constructive and digital

Digital (102, 189, 75)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (27, 70, 37)-net over F₃, using
  - net from sequence [i] based on digital (27, 36)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₃ with g(F)Â =Â 26, N(F)Â =Â 36, and 1 place with degree 2 [i] based on function field F/F₃ with g(F) = 26 and N(F) ≥ 36, using an explicitly constructive algebraic function field [i]
2. digital (32, 119, 38)-net over F₃, using
  - net from sequence [i] based on digital (32, 37)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 32 and N(F) ≥ 38, using
      - an explicitly constructive algebraic function field [i]

(189−87, 189, 120)-Net over F₃ — Digital

Digital (102, 189, 120)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(189−87, 189, 987)-Net in Base 3 — Upper bound on s

There is no (102, 189, 988)-net in base 3, because

1 times m-reduction [i] would yield (102, 188, 988)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 514319 932359 389707 915619 367893 152731 571875 352586 130385 524721 124887 712782 641324 677003 262801 > 3¹⁸⁸ [i]
