Best Known (20, 20+18, s)-Nets in Base 5

(20, 20+18, 54)-Net over F₅ — Constructive and digital

Digital (20, 38, 54)-net over F₅, using

trace code for nets [i] based on digital (1, 19, 27)-net over F₂₅, using
- net from sequence [i] based on digital (1, 26)-sequence over F₂₅, using
  - Niederreiter sequence [i]

(20, 20+18, 72)-Net over F₅ — Digital

Digital (20, 38, 72)-net over F₅, using

trace code for nets [i] based on digital (1, 19, 36)-net over F₂₅, using
- net from sequence [i] based on digital (1, 35)-sequence over F₂₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅ with g(F) = 1 and N(F) ≥ 36, using
    - sharp bound on the number of rational points on curves with genus 1 [i]

(20, 20+18, 920)-Net in Base 5 — Upper bound on s

There is no (20, 38, 921)-net in base 5, because

the generalized Rao bound for nets shows that 5^mÂ â‰¥ 366 001075 050165 534439 296965 > 5³⁸ [i]
