Best Known (6, 6+8, s)-Nets in Base 256

(6, 6+8, 771)-Net over F₂₅₆ — Constructive and digital

Digital (6, 14, 771)-net over F₂₅₆, using

generalized (u,Â u+v)-construction [i] based on
1. digital (0, 2, 257)-net over F₂₅₆, using
  - kÂ =Â 2 construction [i]
2. digital (0, 4, 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]
3. digital (0, 8, 257)-net over F₂₅₆, using
  - net from sequence [i] based on digital (0, 256)-sequence over F₂₅₆ (see above)

(6, 6+8, 1285)-Net over F₂₅₆ — Digital

Digital (6, 14, 1285)-net over F₂₅₆, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OA(256¹⁴, 1285, F₂₅₆, 8) (dual of [1285, 1271, 9]-code), using
- the BCH-code C(I) with length 1285Â | 256²âˆ’1, defining interval IÂ =Â {1,52,103,…,358}, and designed minimum distance dÂ â‰¥Â |I|+1Â =Â 9 [i]

(6, 6+8, 2329980)-Net in Base 256 — Upper bound on s

There is no (6, 14, 2329981)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 5192 304198 563441 272237 144683 496771 > 256¹⁴ [i]
