MinT - Best Known (186−63, 186, s)-Nets in Base 3

Best Known (186−63, 186, s)-Nets in Base 3

(186−63, 186, 156)-Net over F₃ — Constructive and digital

Digital (123, 186, 156)-net over F₃, using

16 times m-reduction [i] based on digital (123, 202, 156)-net over F₃, using
- trace code for nets [i] based on digital (22, 101, 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]

(186−63, 186, 285)-Net over F₃ — Digital

Digital (123, 186, 285)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(186−63, 186, 4338)-Net in Base 3 — Upper bound on s

There is no (123, 186, 4339)-net in base 3, because

1 times m-reduction [i] would yield (123, 185, 4339)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 18621 690138 982868 688007 022807 492041 580515 285988 407104 808254 452683 963852 321620 399614 926227 > 3¹⁸⁵ [i]
