Best Known (139−83, 139, s)-Nets in Base 5

(139−83, 139, 82)-Net over F₅ — Constructive and digital

Digital (56, 139, 82)-net over F₅, using

t-expansion [i] based on digital (48, 139, 82)-net over F₅, using
- net from sequence [i] based on digital (48, 81)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 48 and N(F) ≥ 82, using
    - an explicitly constructive algebraic function field [i]

(139−83, 139, 108)-Net over F₅ — Digital

Digital (56, 139, 108)-net over F₅, using

t-expansion [i] based on digital (55, 139, 108)-net over F₅, using
- net from sequence [i] based on digital (55, 107)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 55 and N(F) ≥ 108, using
    - algebraic function fields over â„¤₅ by Niederreiter/Xing [i]

(139−83, 139, 878)-Net in Base 5 — Upper bound on s

There is no (56, 139, 879)-net in base 5, because

1 times m-reduction [i] would yield (56, 138, 879)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 2 878263 498821 409868 810914 236196 779041 859674 910386 813212 250100 277793 485717 462319 018094 901295 856925 > 5¹³⁸ [i]
