MinT - Best Known (121−79, 121, s)-Nets in Base 8

Best Known (121−79, 121, s)-Nets in Base 8

(121−79, 121, 98)-Net over F₈ — Constructive and digital

Digital (42, 121, 98)-net over F₈, using

t-expansion [i] based on digital (37, 121, 98)-net over F₈, using
- net from sequence [i] based on digital (37, 97)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 37 and N(F) ≥ 98, using
    - F₅ from the tower of function fields over F₈ by van der Geer and van der Vlugt [i]

(121−79, 121, 129)-Net over F₈ — Digital

Digital (42, 121, 129)-net over F₈, using

t-expansion [i] based on digital (38, 121, 129)-net over F₈, using
- net from sequence [i] based on digital (38, 128)-sequence over F₈, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₈ with g(F) = 38 and N(F) ≥ 129, using
    - a curve from the manYPoints database [i]

(121−79, 121, 1297)-Net in Base 8 — Upper bound on s

There is no (42, 121, 1298)-net in base 8, because

1 times m-reduction [i] would yield (42, 120, 1298)-net in base 8, but
- the generalized Rao bound for nets shows that 8^mÂ â‰¥ 2 414424 560355 879265 522717 578336 746995 255360 189152 199328 218305 138721 256332 106822 676615 540524 697955 710323 725760 > 8¹²⁰ [i]
