Best Known (142−89, 142, s)-Nets in Base 3

(142−89, 142, 48)-Net over F₃ — Constructive and digital

Digital (53, 142, 48)-net over F₃, using

t-expansion [i] based on digital (45, 142, 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
    - an explicitly constructive algebraic function field [i]

(142−89, 142, 64)-Net over F₃ — Digital

Digital (53, 142, 64)-net over F₃, using

t-expansion [i] based on digital (49, 142, 64)-net over F₃, using
- net from sequence [i] based on digital (49, 63)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 49 and N(F) ≥ 64, using
    - a curve from the manYPoints database [i]

(142−89, 142, 250)-Net in Base 3 — Upper bound on s

There is no (53, 142, 251)-net in base 3, because

1 times m-reduction [i] would yield (53, 141, 251)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 19 834729 238661 486238 036020 274470 118799 039020 624937 458890 708343 658121 > 3¹⁴¹ [i]
