Best Known (18, 41, s)-Nets in Base 49

(18, 41, 150)-Net over F₄₉ — Constructive and digital

Digital (18, 41, 150)-net over F₄₉, using

generalized (u,Â u+v)-construction [i] based on
1. digital (0, 7, 50)-net over F₄₉, using
  - net from sequence [i] based on digital (0, 49)-sequence over F₄₉, using
    - generalized Faure sequence [i]
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄₉ with g(F) = 0 and N(F) ≥ 50, using
      - the rational function field F₄₉(x) [i]
    - Niederreiter sequence [i]
2. digital (0, 11, 50)-net over F₄₉, using
  - net from sequence [i] based on digital (0, 49)-sequence over F₄₉ (see above)
3. digital (0, 23, 50)-net over F₄₉, using
  - net from sequence [i] based on digital (0, 49)-sequence over F₄₉ (see above)

(18, 41, 277)-Net over F₄₉ — Digital

Digital (18, 41, 277)-net over F₄₉, using

Gilbertâ€“VarÅ¡amov bound [i]

(18, 41, 143193)-Net in Base 49 — Upper bound on s

There is no (18, 41, 143194)-net in base 49, because

1 times m-reduction [i] would yield (18, 40, 143194)-net in base 49, but
- the generalized Rao bound for nets shows that 49^mÂ â‰¥ 40 536418 390474 681468 531873 104740 726982 038801 210769 493704 015229 581985 > 49⁴⁰ [i]
