Best Known (27, 27+121, s)-Nets in Base 9

(27, 27+121, 78)-Net over F₉ — Constructive and digital

Digital (27, 148, 78)-net over F₉, using

t-expansion [i] based on digital (22, 148, 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]

(27, 27+121, 110)-Net over F₉ — Digital

Digital (27, 148, 110)-net over F₉, using

t-expansion [i] based on digital (26, 148, 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]

(27, 27+121, 594)-Net in Base 9 — Upper bound on s

There is no (27, 148, 595)-net in base 9, because

1 times m-reduction [i] would yield (27, 147, 595)-net in base 9, but
- the generalized Rao bound for nets shows that 9^mÂ â‰¥ 191 770259 089277 074722 549332 064884 513606 657371 601235 910276 430952 655781 134039 415039 075153 391564 969994 613629 681610 474905 635154 248312 782880 454305 > 9¹⁴⁷ [i]
