Best Known (5, 5+15, s)-Nets in Base 256

(5, 5+15, 262)-Net over F₂₅₆ — Constructive and digital

Digital (5, 20, 262)-net over F₂₅₆, using

net from sequence [i] based on digital (5, 261)-sequence over F₂₅₆, using
- Niederreiter sequence [i]

(5, 5+15, 321)-Net over F₂₅₆ — Digital

Digital (5, 20, 321)-net over F₂₅₆, using

t-expansion [i] based on digital (2, 20, 321)-net over F₂₅₆, using
- net from sequence [i] based on digital (2, 320)-sequence over F₂₅₆, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅₆ with g(F) = 2 and N(F) ≥ 321, using
    - sharp bound on the number of rational points on curves with genus 2 [i]

(5, 5+15, 45603)-Net in Base 256 — Upper bound on s

There is no (5, 20, 45604)-net in base 256, because

1 times m-reduction [i] would yield (5, 19, 45604)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 5709 171541 417539 720394 407550 258896 041083 629016 > 256¹⁹ [i]
