MinT - Best Known (118, 118+131, s)-Nets in Base 3

Best Known (118, 118+131, s)-Nets in Base 3

(118, 118+131, 75)-Net over F₃ — Constructive and digital

Digital (118, 249, 75)-net over F₃, using

net from sequence [i] based on digital (118, 74)-sequence over F₃, using
- base reduction for sequences [i] based on digital (22, 74)-sequence over F₉, using
  - s-reduction based on digital (22, 77)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 22 and N(F) ≥ 78, using
      - F₃ from the tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(118, 118+131, 120)-Net over F₃ — Digital

Digital (118, 249, 120)-net over F₃, using

t-expansion [i] based on digital (113, 249, 120)-net over F₃, using
- net from sequence [i] based on digital (113, 119)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 113 and N(F) ≥ 120, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(118, 118+131, 765)-Net in Base 3 — Upper bound on s

There is no (118, 249, 766)-net in base 3, because

1 times m-reduction [i] would yield (118, 248, 766)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21847 584075 500781 849011 319151 742053 436148 871124 769014 778003 836635 105457 859633 145594 099587 071647 831870 165013 990916 302205 > 3²⁴⁸ [i]
