Best Known (97−47, 97, s)-Nets in Base 4

(97−47, 97, 66)-Net over F₄ — Constructive and digital

Digital (50, 97, 66)-net over F₄, using

t-expansion [i] based on digital (49, 97, 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]

(97−47, 97, 91)-Net over F₄ — Digital

Digital (50, 97, 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]

(97−47, 97, 1005)-Net in Base 4 — Upper bound on s

There is no (50, 97, 1006)-net in base 4, because

1 times m-reduction [i] would yield (50, 96, 1006)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 6359 560562 786721 366855 639014 696569 191377 137738 727951 266936 > 4⁹⁶ [i]
