Best Known (68, 68+49, s)-Nets in Base 9

(68, 68+49, 344)-Net over F₉ — Constructive and digital

Digital (68, 117, 344)-net over F₉, using

5 times m-reduction [i] based on digital (68, 122, 344)-net over F₉, using
- trace code for nets [i] based on digital (7, 61, 172)-net over F₈₁, using
  - net from sequence [i] based on digital (7, 171)-sequence over F₈₁, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈₁ with g(F) = 7 and N(F) ≥ 172, using
      - a function field by SÃ©mirat [i]

(68, 68+49, 496)-Net over F₉ — Digital

Digital (68, 117, 496)-net over F₉, using

Gilbertâ€“VarÅ¡amov bound [i]

(68, 68+49, 50155)-Net in Base 9 — Upper bound on s

There is no (68, 117, 50156)-net in base 9, because

1 times m-reduction [i] would yield (68, 116, 50156)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 492 284383 847425 535543 554966 191504 801743 638701 635538 662915 270959 201706 233207 221598 831471 313045 903625 591322 281729 > 9¹¹⁶ [i]
