Best Known (4, 4+35, s)-Nets in Base 64

(4, 4+35, 104)-Net over F₆₄ — Constructive and digital

Digital (4, 39, 104)-net over F₆₄, using

t-expansion [i] based on digital (3, 39, 104)-net over F₆₄, using
- net from sequence [i] based on digital (3, 103)-sequence over F₆₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 3 and N(F) ≥ 104, using
    - a function field by SÃ©mirat [i]

(4, 4+35, 129)-Net over F₆₄ — Digital

Digital (4, 39, 129)-net over F₆₄, using

net from sequence [i] based on digital (4, 128)-sequence over F₆₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 4 and N(F) ≥ 129, using
  - K_1,1 from the tower of function fields by Niederreiter and Xing based on the tower by GarcÃa and Stichtenoth over F₆₄ [i]

(4, 4+35, 1233)-Net in Base 64 — Upper bound on s

There is no (4, 39, 1234)-net in base 64, because

1 times m-reduction [i] would yield (4, 38, 1234)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 435 836882 872393 404325 872436 858586 024784 864499 749672 701938 129687 701115 > 64³⁸ [i]
