    - 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 (1, 10, 258)-net over F₂₅₆, using

(5, 5+9, 546)-Net over F₂₅₆ — Digital

Digital (5, 14, 546)-net over F₂₅₆, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(256¹⁴, 546, F₂₅₆, 2, 9) (dual of [(546, 2), 1078, 10]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(256⁴, 257, F₂₅₆, 2, 4) (dual of [(257, 2), 510, 5]-NRT-code), using
    - extended Reedâ€“Solomon NRT-code RS_e(2;510,256) [i]
  2. linear OOA(256¹⁰, 289, F₂₅₆, 2, 9) (dual of [(289, 2), 568, 10]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(2;F,568P) [i] based on function field F/F₂₅₆ with g(F) = 1 and N(F) ≥ 289, using
      - sharp bound on the number of rational points on curves with genus 1 [i]

(5, 5+9, 582493)-Net in Base 256 — Upper bound on s

There is no (5, 14, 582494)-net in base 256, because

1 times m-reduction [i] would yield (5, 13, 582494)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 20 282422 504132 163617 165016 448631 > 256¹³ [i]
