Best Known (80, 80+91, s)-Nets in Base 3

(80, 80+91, 56)-Net over F₃ — Constructive and digital

Digital (80, 171, 56)-net over F₃, using

9 times m-reduction [i] based on digital (80, 180, 56)-net over F₃, using
- (u,Â u+v)-construction [i] based on
  1. digital (15, 65, 28)-net over F₃, using
    - net from sequence [i] based on digital (15, 27)-sequence over F₃, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 15 and N(F) ≥ 28, using
        an explicitly constructive algebraic function field [i]
  2. digital (15, 115, 28)-net over F₃, using
    - net from sequence [i] based on digital (15, 27)-sequence over F₃ (see above)

(80, 80+91, 84)-Net over F₃ — Digital

Digital (80, 171, 84)-net over F₃, using

t-expansion [i] based on digital (71, 171, 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+91, 516)-Net in Base 3 — Upper bound on s

There is no (80, 171, 517)-net in base 3, because

1 times m-reduction [i] would yield (80, 170, 517)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1380 463993 031102 595535 889418 155695 824615 788939 662047 515113 190256 994250 336057 481339 > 3¹⁷⁰ [i]
