Best Known (50, 111, s)-Nets in Base 4

(50, 111, 66)-Net over F₄ — Constructive and digital

Digital (50, 111, 66)-net over F₄, using

t-expansion [i] based on digital (49, 111, 66)-net over F₄, using
- net from sequence [i] based on digital (49, 65)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 49 and N(F) ≥ 66, using
    - T₆ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(50, 111, 91)-Net over F₄ — Digital

Digital (50, 111, 91)-net over F₄, using

net from sequence [i] based on digital (50, 90)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 50 and N(F) ≥ 91, using
  - a curve from the manYPoints database [i]

(50, 111, 623)-Net in Base 4 — Upper bound on s

There is no (50, 111, 624)-net in base 4, because

1 times m-reduction [i] would yield (50, 110, 624)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1 738842 191046 605719 540833 733167 378444 190621 503687 516023 449842 557986 > 4¹¹⁰ [i]
