Best Known (159, 159+81, s)-Nets in Base 3

(159, 159+81, 162)-Net over F₃ — Constructive and digital

Digital (159, 240, 162)-net over F₃, using

t-expansion [i] based on digital (157, 240, 162)-net over F₃, using
- 10 times m-reduction [i] based on digital (157, 250, 162)-net over F₃, using
  - trace code for nets [i] based on digital (32, 125, 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]

(159, 159+81, 359)-Net over F₃ — Digital

Digital (159, 240, 359)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(159, 159+81, 5552)-Net in Base 3 — Upper bound on s

There is no (159, 240, 5553)-net in base 3, because

1 times m-reduction [i] would yield (159, 239, 5553)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1 080025 439257 081365 523071 220269 910891 242478 724221 487771 061583 738347 775635 197482 240813 635886 697463 449261 514179 239969 > 3²³⁹ [i]
