Best Known (160, 160+87, s)-Nets in Base 3

(160, 160+87, 162)-Net over F₃ — Constructive and digital

Digital (160, 247, 162)-net over F₃, using

t-expansion [i] based on digital (157, 247, 162)-net over F₃, using
- 3 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]

(160, 160+87, 324)-Net over F₃ — Digital

Digital (160, 247, 324)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(160, 160+87, 4486)-Net in Base 3 — Upper bound on s

There is no (160, 247, 4487)-net in base 3, because

1 times m-reduction [i] would yield (160, 246, 4487)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2358 422449 808579 713598 379216 018560 943976 580401 504388 782694 096061 946620 024883 667270 533030 709146 364926 780461 705611 191371 > 3²⁴⁶ [i]
