MinT - Best Known (147−117, 147, s)-Nets in Base 9

Best Known (147−117, 147, s)-Nets in Base 9

(147−117, 147, 78)-Net over F₉ — Constructive and digital

Digital (30, 147, 78)-net over F₉, using

t-expansion [i] based on digital (22, 147, 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]

(147−117, 147, 110)-Net over F₉ — Digital

Digital (30, 147, 110)-net over F₉, using

t-expansion [i] based on digital (26, 147, 110)-net over F₉, using
- net from sequence [i] based on digital (26, 109)-sequence over F₉, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 26 and N(F) ≥ 110, using
    - a curve from the manYPoints database [i]

(147−117, 147, 673)-Net in Base 9 — Upper bound on s

There is no (30, 147, 674)-net in base 9, because

1 times m-reduction [i] would yield (30, 146, 674)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 22 587945 806434 796179 034659 996180 218821 395587 026685 679277 439832 374284 195407 154034 241102 207246 803360 630459 071884 322617 519163 811017 619407 614305 > 9¹⁴⁶ [i]
