Best Known (66, 135, s)-Nets in Base 4

(66, 135, 66)-Net over F₄ — Constructive and digital

Digital (66, 135, 66)-net over F₄, using

t-expansion [i] based on digital (49, 135, 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]

(66, 135, 99)-Net over F₄ — Digital

Digital (66, 135, 99)-net over F₄, using

t-expansion [i] based on digital (61, 135, 99)-net over F₄, using
- net from sequence [i] based on digital (61, 98)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 61 and N(F) ≥ 99, using
    - Drinfeld modules of rank 1 [i]

(66, 135, 1037)-Net in Base 4 — Upper bound on s

There is no (66, 135, 1038)-net in base 4, because

1 times m-reduction [i] would yield (66, 134, 1038)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 489 304333 955924 893143 933628 270654 932984 081155 903846 335328 624377 529174 740753 384000 > 4¹³⁴ [i]
