Best Known (91, 238, s)-Nets in Base 3

(91, 238, 64)-Net over F₃ — Constructive and digital

Digital (91, 238, 64)-net over F₃, using

t-expansion [i] based on digital (89, 238, 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]

(91, 238, 96)-Net over F₃ — Digital

Digital (91, 238, 96)-net over F₃, using

t-expansion [i] based on digital (89, 238, 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]

(91, 238, 427)-Net in Base 3 — Upper bound on s

There is no (91, 238, 428)-net in base 3, because

1 times m-reduction [i] would yield (91, 237, 428)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 132269 196612 769533 031695 896130 592017 663251 449239 915213 905996 437379 859036 982308 179241 286336 121248 240702 094057 554137 > 3²³⁷ [i]
