MinT - Best Known (21−16, 21, s)-Nets in Base 25

Best Known (21−16, 21, s)-Nets in Base 25

(21−16, 21, 66)-Net over F₂₅ — Constructive and digital

Digital (5, 21, 66)-net over F₂₅, using

t-expansion [i] based on digital (4, 21, 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]

(21−16, 21, 729)-Net in Base 25 — Upper bound on s

There is no (5, 21, 730)-net in base 25, because

the generalized Rao bound for nets shows that 25^mÂ â‰¥ 229574 758971 154672 764448 408705 > 25²¹ [i]
