(29−19, 29, 546)-Net over F₂₅₆ — Digital

Digital (10, 29, 546)-net over F₂₅₆, using

embedding of OOA with Gilbertâ€“VarÅ¡amov bound [i] based on linear OOA(256²⁹, 546, F₂₅₆, 5, 19) (dual of [(546, 5), 2701, 20]-NRT-code), using
- (u,Â u+v)-construction [i] based on
  1. linear OOA(256⁹, 257, F₂₅₆, 5, 9) (dual of [(257, 5), 1276, 10]-NRT-code), using
    - extended Reedâ€“Solomon NRT-code RS_e(5;1276,256) [i]
  2. linear OOA(256²⁰, 289, F₂₅₆, 5, 19) (dual of [(289, 5), 1425, 20]-NRT-code), using
    - extended algebraic-geometric NRT-code AG_e(5;F,1425P) [i] based on function field F/F₂₅₆ with g(F) = 1 and N(F) ≥ 289, using

(29−19, 29, 505254)-Net in Base 256 — Upper bound on s

There is no (10, 29, 505255)-net in base 256, because

1 times m-reduction [i] would yield (10, 28, 505255)-net in base 256, but
- the generalized Rao bound for nets shows that 256^mÂ â‰¥ 26 960341 420696 499919 310274 445174 000802 440001 217674 717819 227143 559976 > 256²⁸ [i]
