Best Known (139, 139+69, s)-Nets in Base 3

(139, 139+69, 162)-Net over F₃ — Constructive and digital

Digital (139, 208, 162)-net over F₃, using

6 times m-reduction [i] based on digital (139, 214, 162)-net over F₃, using
- trace code for nets [i] based on digital (32, 107, 81)-net over F₉, using
  - net from sequence [i] based on digital (32, 80)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 32 and N(F) ≥ 81, using
      - F₄ from the tower of function fields by Bezerra and GarcÃa over F₉ [i]

(139, 139+69, 334)-Net over F₃ — Digital

Digital (139, 208, 334)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(139, 139+69, 5402)-Net in Base 3 — Upper bound on s

There is no (139, 208, 5403)-net in base 3, because

1 times m-reduction [i] would yield (139, 207, 5403)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 582 748484 093938 456115 466347 874249 053681 840973 492208 550646 670491 571254 780319 010148 568429 769097 103125 > 3²⁰⁷ [i]
