Best Known (65, 65+69, s)-Nets in Base 4

(65, 65+69, 66)-Net over F₄ — Constructive and digital

Digital (65, 134, 66)-net over F₄, using

t-expansion [i] based on digital (49, 134, 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]

(65, 65+69, 99)-Net over F₄ — Digital

Digital (65, 134, 99)-net over F₄, using

t-expansion [i] based on digital (61, 134, 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]

(65, 65+69, 994)-Net in Base 4 — Upper bound on s

There is no (65, 134, 995)-net in base 4, because

1 times m-reduction [i] would yield (65, 133, 995)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 120 554461 799974 352260 884032 942889 229731 673661 827599 482042 265184 799607 531363 857083 > 4¹³³ [i]
