MinT - Best Known (4, 21, s)-Nets in Base 49

Best Known (4, 21, s)-Nets in Base 49

(4, 21, 54)-Net over F₄₉ — Constructive and digital

Digital (4, 21, 54)-net over F₄₉, using

net from sequence [i] based on digital (4, 53)-sequence over F₄₉, using
- Niederreiter sequence [i]

(4, 21, 92)-Net over F₄₉ — Digital

Digital (4, 21, 92)-net over F₄₉, using

t-expansion [i] based on digital (3, 21, 92)-net over F₄₉, using
- net from sequence [i] based on digital (3, 91)-sequence over F₄₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄₉ with g(F) = 3 and N(F) ≥ 92, using
    - a curve from the manYPoints database [i]

(4, 21, 1314)-Net in Base 49 — Upper bound on s

There is no (4, 21, 1315)-net in base 49, because

1 times m-reduction [i] would yield (4, 20, 1315)-net in base 49, but
- the generalized Rao bound for nets shows that 49^mÂ â‰¥ 6389 739726 804818 048231 406736 301185 > 49²⁰ [i]
