Best Known (189−89, 189, s)-Nets in Base 3

(189−89, 189, 74)-Net over F₃ — Constructive and digital

Digital (100, 189, 74)-net over F₃, using

3 times m-reduction [i] based on digital (100, 192, 74)-net over F₃, using
- (u,Â u+v)-construction [i] based on
  1. digital (27, 73, 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 (27, 119, 37)-net over F₃, using
    - net from sequence [i] based on digital (27, 36)-sequence over F₃ (see above)

(189−89, 189, 113)-Net over F₃ — Digital

Digital (100, 189, 113)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(189−89, 189, 900)-Net in Base 3 — Upper bound on s

There is no (100, 189, 901)-net in base 3, because

1 times m-reduction [i] would yield (100, 188, 901)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 516525 570449 903600 809376 037517 181697 282202 861046 690581 055855 761042 104798 795576 197860 543665 > 3¹⁸⁸ [i]
