(46−29, 46, 610)-Net over F₂₅₆ — Digital

Digital (17, 46, 610)-net over F₂₅₆, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(256⁴⁶, 610, F₂₅₆, 4, 29) (dual of [(610, 4), 2394, 30]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(256¹⁵, 289, F₂₅₆, 4, 14) (dual of [(289, 4), 1141, 15]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(4;F,1141P) [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]
  2. linear OOA(256³¹, 321, F₂₅₆, 4, 29) (dual of [(321, 4), 1253, 30]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(4;F,1254P) [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]

(46−29, 46, 1305228)-Net in Base 256 — Upper bound on s

There is no (17, 46, 1305229)-net in base 256, because

1 times m-reduction [i] would yield (17, 45, 1305229)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 2 348544 057432 387454 172704 174962 714174 580307 374235 363792 891869 768411 902322 788472 721099 528982 815277 111458 414656 > 256⁴⁵ [i]
