(17−11, 17, 546)-Net over F₂₅₆ — Digital

Digital (6, 17, 546)-net over F₂₅₆, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(256¹⁷, 546, F₂₅₆, 3, 11) (dual of [(546, 3), 1621, 12]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(256⁵, 257, F₂₅₆, 3, 5) (dual of [(257, 3), 766, 6]-NRT-code), using
    - extended Reedâ€“Solomon NRT-code RS_e(3;766,256) [i]
  2. linear OOA(256¹², 289, F₂₅₆, 3, 11) (dual of [(289, 3), 855, 12]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(3;F,855P) [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]

(17−11, 17, 519591)-Net in Base 256 — Upper bound on s

There is no (6, 17, 519592)-net in base 256, because

1 times m-reduction [i] would yield (6, 16, 519592)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 340 283095 752478 887489 893638 475947 348051 > 256¹⁶ [i]
