Best Known (12, 12+41, s)-Nets in Base 64

(12, 12+41, 177)-Net over F₆₄ — Constructive and digital

Digital (12, 53, 177)-net over F₆₄, using

t-expansion [i] based on digital (7, 53, 177)-net over F₆₄, using

(12, 12+41, 257)-Net over F₆₄ — Digital

Digital (12, 53, 257)-net over F₆₄, using

net from sequence [i] based on digital (12, 256)-sequence over F₆₄, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₆₄ with g(F) = 12 and N(F) ≥ 257, using

(12, 12+41, 6537)-Net in Base 64 — Upper bound on s

There is no (12, 53, 6538)-net in base 64, because

1 times m-reduction [i] would yield (12, 52, 6538)-net in base 64, but
- the generalized Rao bound for nets shows that 64^mÂ â‰¥ 8367 845585 839224 639796 643529 125769 368400 669137 236584 456738 225725 752228 720313 406016 793785 854256 > 64⁵² [i]
