Best Known (4, 4+21, s)-Nets in Base 16

(4, 4+21, 45)-Net over F₁₆ — Constructive and digital

Digital (4, 25, 45)-net over F₁₆, using

net from sequence [i] based on digital (4, 44)-sequence over F₁₆, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₁₆ with g(F) = 4 and N(F) ≥ 45, using
  - a function field by GarcÃa and Quoos [i]

(4, 4+21, 229)-Net in Base 16 — Upper bound on s

There is no (4, 25, 230)-net in base 16, because

1 times m-reduction [i] would yield (4, 24, 230)-net in base 16, but
- the generalized Rao bound for nets shows that 16^mÂ â‰¥ 82098 462385 539373 739645 886376 > 16²⁴ [i]
