Best Known (76−61, 76, s)-Nets in Base 64

(76−61, 76, 177)-Net over F₆₄ — Constructive and digital

Digital (15, 76, 177)-net over F₆₄, using

t-expansion [i] based on digital (7, 76, 177)-net over F₆₄, using
- net from sequence [i] based on digital (7, 176)-sequence over F₆₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 7 and N(F) ≥ 177, using
    - a function field by GarcÃa and Quoos [i]

      - a function field by SÃ©mirat [i]

(76−61, 76, 258)-Net over F₆₄ — Digital

Digital (15, 76, 258)-net over F₆₄, using

net from sequence [i] based on digital (15, 257)-sequence over F₆₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 15 and N(F) ≥ 258, using

(76−61, 76, 6249)-Net in Base 64 — Upper bound on s

There is no (15, 76, 6250)-net in base 64, because

1 times m-reduction [i] would yield (15, 75, 6250)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 2911 550952 440830 828709 884948 158684 960137 081854 840735 561093 422831 651330 867942 460251 417260 332836 397395 979991 869789 984072 408290 082363 251376 > 64⁷⁵ [i]
