Best Known (90, 90+133, s)-Nets in Base 3

(90, 90+133, 64)-Net over F₃ — Constructive and digital

Digital (90, 223, 64)-net over F₃, using

t-expansion [i] based on digital (89, 223, 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]

(90, 90+133, 96)-Net over F₃ — Digital

Digital (90, 223, 96)-net over F₃, using

t-expansion [i] based on digital (89, 223, 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]

(90, 90+133, 449)-Net in Base 3 — Upper bound on s

There is no (90, 223, 450)-net in base 3, because

1 times m-reduction [i] would yield (90, 222, 450)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 9061 978033 072188 238897 038126 806615 306929 995180 262432 854043 048379 306032 923945 227758 571209 889742 377260 382997 > 3²²² [i]
