Best Known (20, 49, s)-Nets in Base 5

(20, 49, 43)-Net over F₅ — Constructive and digital

Digital (20, 49, 43)-net over F₅, using

t-expansion [i] based on digital (18, 49, 43)-net over F₅, using
- net from sequence [i] based on digital (18, 42)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₅ with g(F)Â =Â 17, N(F)Â =Â 42, and 1 place with degree 2 [i] based on function field F/F₅ with g(F) = 17 and N(F) ≥ 42, using an explicitly constructive algebraic function field [i]

(20, 49, 45)-Net over F₅ — Digital

Digital (20, 49, 45)-net over F₅, using

t-expansion [i] based on digital (19, 49, 45)-net over F₅, using
- net from sequence [i] based on digital (19, 44)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 19 and N(F) ≥ 45, using
    - algebraic function fields over â„¤₅ by Niederreiter/Xing [i]

(20, 49, 366)-Net in Base 5 — Upper bound on s

There is no (20, 49, 367)-net in base 5, because

1 times m-reduction [i] would yield (20, 48, 367)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 3594 716746 822162 685200 565444 953545 > 5⁴⁸ [i]
