Best Known (91, 91+87, s)-Nets in Base 3

(91, 91+87, 69)-Net over F₃ — Constructive and digital

Digital (91, 178, 69)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (21, 64, 32)-net over F₃, using
  - net from sequence [i] based on digital (21, 31)-sequence over F₃, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 21 and N(F) ≥ 32, using
      - an explicitly constructive algebraic function field [i]
2. digital (27, 114, 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]

(91, 91+87, 96)-Net over F₃ — Digital

Digital (91, 178, 96)-net over F₃, using

t-expansion [i] based on digital (89, 178, 96)-net over F₃, using
- net from sequence [i] based on digital (89, 95)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 89 and N(F) ≥ 96, using

(91, 91+87, 735)-Net in Base 3 — Upper bound on s

There is no (91, 178, 736)-net in base 3, because

1 times m-reduction [i] would yield (91, 177, 736)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2 915266 648477 458859 199716 135447 505419 864739 576909 955240 086024 707647 023644 487516 406657 > 3¹⁷⁷ [i]
