MinT - Best Known (206−77, 206, s)-Nets in Base 3

Best Known (206−77, 206, s)-Nets in Base 3

(206−77, 206, 156)-Net over F₃ — Constructive and digital

Digital (129, 206, 156)-net over F₃, using

8 times m-reduction [i] based on digital (129, 214, 156)-net over F₃, using
- trace code for nets [i] based on digital (22, 107, 78)-net over F₉, using
  - net from sequence [i] 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]

(206−77, 206, 233)-Net over F₃ — Digital

Digital (129, 206, 233)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(206−77, 206, 2779)-Net in Base 3 — Upper bound on s

There is no (129, 206, 2780)-net in base 3, because

1 times m-reduction [i] would yield (129, 205, 2780)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 65 198330 688696 674402 613643 430798 737968 057297 741633 562700 231291 740586 086038 019065 918094 389147 769065 > 3²⁰⁵ [i]
