Best Known (249−117, 249, s)-Nets in Base 3

(249−117, 249, 85)-Net over F₃ — Constructive and digital

Digital (132, 249, 85)-net over F₃, using

t-expansion [i] based on digital (131, 249, 85)-net over F₃, using
- (u,Â u+v)-construction [i] based on
  1. digital (27, 86, 37)-net over F₃, using
    - net from sequence [i] based on digital (27, 36)-sequence over F₃, using
      - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₃ with g(F)Â =Â 26, N(F)Â =Â 36, and 1 place with degree 2 [i] based on function field F/F₃ with g(F) = 26 and N(F) ≥ 36, using an explicitly constructive algebraic function field [i]
  2. digital (45, 163, 48)-net over F₃, using
    - net from sequence [i] based on digital (45, 47)-sequence over F₃, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 45 and N(F) ≥ 48, using

(249−117, 249, 144)-Net over F₃ — Digital

Digital (132, 249, 144)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(249−117, 249, 1174)-Net in Base 3 — Upper bound on s

There is no (132, 249, 1175)-net in base 3, because

1 times m-reduction [i] would yield (132, 248, 1175)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21473 106325 175478 648730 502541 246842 317353 498643 768311 833239 809481 497185 794642 177643 335282 015076 158810 966473 165599 045181 > 3²⁴⁸ [i]
