Best Known (70, 185, s)-Nets in Base 4

(70, 185, 66)-Net over F₄ — Constructive and digital

Digital (70, 185, 66)-net over F₄, using

t-expansion [i] based on digital (49, 185, 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]

(70, 185, 105)-Net over F₄ — Digital

Digital (70, 185, 105)-net over F₄, using

net from sequence [i] based on digital (70, 104)-sequence over F₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 70 and N(F) ≥ 105, using
  - Drinfeld modules of rank 1 [i]

(70, 185, 600)-Net in Base 4 — Upper bound on s

There is no (70, 185, 601)-net in base 4, because

1 times m-reduction [i] would yield (70, 184, 601)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 630 746826 898616 047633 163996 285587 004261 583570 509178 052798 648980 539186 938185 705829 290173 156480 944780 933869 982504 > 4¹⁸⁴ [i]
