Best Known (131−89, 131, s)-Nets in Base 5

(131−89, 131, 78)-Net over F₅ — Constructive and digital

Digital (42, 131, 78)-net over F₅, using

t-expansion [i] based on digital (38, 131, 78)-net over F₅, using
- net from sequence [i] based on digital (38, 77)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 38 and N(F) ≥ 78, using
    - an explicitly constructive algebraic function field [i]

(131−89, 131, 80)-Net over F₅ — Digital

Digital (42, 131, 80)-net over F₅, using

t-expansion [i] based on digital (41, 131, 80)-net over F₅, using
- net from sequence [i] based on digital (41, 79)-sequence over F₅, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₅ with g(F) = 41 and N(F) ≥ 80, using
    - algebraic function fields over â„¤₅ by Niederreiter/Xing [i]

(131−89, 131, 469)-Net in Base 5 — Upper bound on s

There is no (42, 131, 470)-net in base 5, because

1 times m-reduction [i] would yield (42, 130, 470)-net in base 5, but
- the generalized Rao bound for nets shows that 5^mÂ â‰¥ 7 733518 929308 234232 015073 810109 642050 938759 345635 434739 138504 507951 708623 143038 727134 555073 > 5¹³⁰ [i]
