MinT - Best Known (120−81, 120, s)-Nets in Base 9

Best Known (120−81, 120, s)-Nets in Base 9

(120−81, 120, 81)-Net over F₉ — Constructive and digital

Digital (39, 120, 81)-net over F₉, using

t-expansion [i] based on digital (32, 120, 81)-net over F₉, using
- net from sequence [i] based on digital (32, 80)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 32 and N(F) ≥ 81, using
    - F₄ from the tower of function fields by Bezerra and GarcÃa over F₉ [i]

(120−81, 120, 140)-Net over F₉ — Digital

Digital (39, 120, 140)-net over F₉, using

net from sequence [i] based on digital (39, 139)-sequence over F₉, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 39 and N(F) ≥ 140, using
  - a curve from the manYPoints database [i]

(120−81, 120, 1335)-Net in Base 9 — Upper bound on s

There is no (39, 120, 1336)-net in base 9, because

1 times m-reduction [i] would yield (39, 119, 1336)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 361620 527087 986032 155269 640961 246944 263690 763754 521682 008082 767808 098611 584945 839674 264822 782184 889531 507407 092225 > 9¹¹⁹ [i]
