MinT - Best Known (28, 28+21, s)-Nets in Base 3

Best Known (28, 28+21, s)-Nets in Base 3

(28, 28+21, 56)-Net over F₃ — Constructive and digital

Digital (28, 49, 56)-net over F₃, using

1 times m-reduction [i] based on digital (28, 50, 56)-net over F₃, using
- trace code for nets [i] based on digital (3, 25, 28)-net over F₉, using
  - net from sequence [i] based on digital (3, 27)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 3 and N(F) ≥ 28, using
      - the Hermitian function field over F₉ [i]

(28, 28+21, 432)-Net in Base 3 — Upper bound on s

There is no (28, 49, 433)-net in base 3, because

1 times m-reduction [i] would yield (28, 48, 433)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 81065 906093 073675 641481 > 3⁴⁸ [i]
