Best Known (80, 80+137, s)-Nets in Base 3

(80, 80+137, 55)-Net over F₃ — Constructive and digital

Digital (80, 217, 55)-net over F₃, using

net from sequence [i] based on digital (80, 54)-sequence over F₃, using
- base reduction for sequences [i] based on digital (13, 54)-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]

(80, 80+137, 84)-Net over F₃ — Digital

Digital (80, 217, 84)-net over F₃, using

t-expansion [i] based on digital (71, 217, 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]

(80, 80+137, 365)-Net in Base 3 — Upper bound on s

There is no (80, 217, 366)-net in base 3, because

1 times m-reduction [i] would yield (80, 216, 366)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 12 942436 986976 714630 974236 008200 277299 564752 000365 273775 300579 704895 509175 477714 094251 448932 841322 064265 > 3²¹⁶ [i]
