MinT - Best Known (246−97, 246, s)-Nets in Base 3

Best Known (246−97, 246, s)-Nets in Base 3

(246−97, 246, 156)-Net over F₃ — Constructive and digital

Digital (149, 246, 156)-net over F₃, using

t-expansion [i] based on digital (147, 246, 156)-net over F₃, using
- 4 times m-reduction [i] based on digital (147, 250, 156)-net over F₃, using
  - trace code for nets [i] based on digital (22, 125, 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]

(246−97, 246, 233)-Net over F₃ — Digital

Digital (149, 246, 233)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(246−97, 246, 2505)-Net in Base 3 — Upper bound on s

There is no (149, 246, 2506)-net in base 3, because

1 times m-reduction [i] would yield (149, 245, 2506)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 785 366064 004492 989751 869819 935154 658649 491718 644434 313221 314902 119302 837693 138901 200064 256166 674826 321856 429079 926497 > 3²⁴⁵ [i]
