Best Known (64, 64+111, s)-Nets in Base 4

(64, 64+111, 66)-Net over F₄ — Constructive and digital

Digital (64, 175, 66)-net over F₄, using

t-expansion [i] based on digital (49, 175, 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]

(64, 64+111, 99)-Net over F₄ — Digital

Digital (64, 175, 99)-net over F₄, using

t-expansion [i] based on digital (61, 175, 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]

(64, 64+111, 527)-Net in Base 4 — Upper bound on s

There is no (64, 175, 528)-net in base 4, because

1 times m-reduction [i] would yield (64, 174, 528)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 624 272577 824860 300083 742067 105418 573035 112452 389361 070343 235959 086239 497465 495956 878924 375445 975412 862560 > 4¹⁷⁴ [i]
