Best Known (65, 65+71, s)-Nets in Base 4

(65, 65+71, 66)-Net over F₄ — Constructive and digital

Digital (65, 136, 66)-net over F₄, using

t-expansion [i] based on digital (49, 136, 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+71, 99)-Net over F₄ — Digital

Digital (65, 136, 99)-net over F₄, using

t-expansion [i] based on digital (61, 136, 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+71, 945)-Net in Base 4 — Upper bound on s

There is no (65, 136, 946)-net in base 4, because

1 times m-reduction [i] would yield (65, 135, 946)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 1949 857734 613401 807140 572926 572002 377550 223560 361552 199784 871033 076542 734850 879800 > 4¹³⁵ [i]
