MinT - Best Known (138, 138+85, s)-Nets in Base 3

Best Known (138, 138+85, s)-Nets in Base 3

(138, 138+85, 156)-Net over F₃ — Constructive and digital

Digital (138, 223, 156)-net over F₃, using

9 times m-reduction [i] based on digital (138, 232, 156)-net over F₃, using
- trace code for nets [i] based on digital (22, 116, 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]

(138, 138+85, 236)-Net over F₃ — Digital

Digital (138, 223, 236)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(138, 138+85, 2704)-Net in Base 3 — Upper bound on s

There is no (138, 223, 2705)-net in base 3, because

1 times m-reduction [i] would yield (138, 222, 2705)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 8367 592476 992823 014353 841563 695650 869891 889780 020992 113278 683832 723840 469577 034536 363256 668679 915531 568073 > 3²²² [i]
