MinT - Best Known (121, 121+63, s)-Nets in Base 3

Best Known (121, 121+63, s)-Nets in Base 3

(121, 121+63, 156)-Net over F₃ — Constructive and digital

Digital (121, 184, 156)-net over F₃, using

14 times m-reduction [i] based on digital (121, 198, 156)-net over F₃, using
- trace code for nets [i] based on digital (22, 99, 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]

(121, 121+63, 273)-Net over F₃ — Digital

Digital (121, 184, 273)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(121, 121+63, 4039)-Net in Base 3 — Upper bound on s

There is no (121, 184, 4040)-net in base 3, because

1 times m-reduction [i] would yield (121, 183, 4040)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2068 588349 590764 233472 802819 707605 400734 121156 942391 918435 304590 167305 634852 697675 372385 > 3¹⁸³ [i]
