Best Known (12, 12+25, s)-Nets in Base 256

(12, 12+25, 514)-Net over F₂₅₆ — Constructive and digital

Digital (12, 37, 514)-net over F₂₅₆, using

(u,Â u+v)-construction [i] based on
1. digital (0, 12, 257)-net over F₂₅₆, using
  - net from sequence [i] based on digital (0, 256)-sequence over F₂₅₆, using
    - generalized Faure sequence [i]
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₅₆ with g(F) = 0 and N(F) ≥ 257, using
      - the rational function field F₂₅₆(x) [i]
    - Niederreiter sequence [i]
2. digital (0, 25, 257)-net over F₂₅₆, using
  - net from sequence [i] based on digital (0, 256)-sequence over F₂₅₆ (see above)

(12, 12+25, 347963)-Net in Base 256 — Upper bound on s

There is no (12, 37, 347964)-net in base 256, because

1 times m-reduction [i] would yield (12, 36, 347964)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 497 324729 410761 028256 470026 937108 921296 180190 685376 479181 899040 393175 541489 113827 968716 > 256³⁶ [i]
