MinT - Best Known (197−71, 197, s)-Nets in Base 3

Best Known (197−71, 197, s)-Nets in Base 3

(197−71, 197, 156)-Net over F₃ — Constructive and digital

Digital (126, 197, 156)-net over F₃, using

11 times m-reduction [i] based on digital (126, 208, 156)-net over F₃, using
- trace code for nets [i] based on digital (22, 104, 78)-net over F₉, using
  - net from sequence [i] based on digital (22, 77)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 22 and N(F) ≥ 78, using
      - F₃ from the tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(197−71, 197, 248)-Net over F₃ — Digital

Digital (126, 197, 248)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(197−71, 197, 3232)-Net in Base 3 — Upper bound on s

There is no (126, 197, 3233)-net in base 3, because

1 times m-reduction [i] would yield (126, 196, 3233)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3301 104820 870450 592851 943195 269100 061746 178166 767995 777559 967618 299481 857330 557398 835883 773211 > 3¹⁹⁶ [i]
