MinT - Best Known (7, 48, s)-Nets in Base 25

Best Known (7, 48, s)-Nets in Base 25

(7, 48, 66)-Net over F₂₅ — Constructive and digital

Digital (7, 48, 66)-net over F₂₅, using

t-expansion [i] based on digital (4, 48, 66)-net over F₂₅, using
- net from sequence [i] based on digital (4, 65)-sequence over F₂₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 4 and N(F) ≥ 66, using
    - a function field by GarcÃa and Quoos [i]

(7, 48, 656)-Net in Base 25 — Upper bound on s

There is no (7, 48, 657)-net in base 25, because

1 times m-reduction [i] would yield (7, 47, 657)-net in base 25, but
- the generalized Rao bound for nets shows that 25^mÂ â‰¥ 506375 856385 845696 075734 931905 735711 795837 326857 932767 337069 492065 > 25⁴⁷ [i]
