Best Known (21, 21+73, s)-Nets in Base 25

(21, 21+73, 148)-Net over F₂₅ — Constructive and digital

Digital (21, 94, 148)-net over F₂₅, using

t-expansion [i] based on digital (19, 94, 148)-net over F₂₅, using
- net from sequence [i] based on digital (19, 147)-sequence over F₂₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 19 and N(F) ≥ 148, using
    - a function field by GarcÃa and Quoos [i]

(21, 21+73, 171)-Net over F₂₅ — Digital

Digital (21, 94, 171)-net over F₂₅, using

t-expansion [i] based on digital (20, 94, 171)-net over F₂₅, using
- net from sequence [i] based on digital (20, 170)-sequence over F₂₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 20 and N(F) ≥ 171, using
    - an algebraic function field by Teo [i]

(21, 21+73, 2412)-Net in Base 25 — Upper bound on s

There is no (21, 94, 2413)-net in base 25, because

1 times m-reduction [i] would yield (21, 93, 2413)-net in base 25, but
- the generalized Rao bound for nets shows that 25^mÂ â‰¥ 10269 363808 107222 577047 532585 028640 023175 519881 778469 143360 947680 101392 185268 484084 982723 720513 077468 865209 285605 997436 876719 943777 > 25⁹³ [i]
