MinT - Best Known (169−81, 169, s)-Nets in Base 3

Best Known (169−81, 169, s)-Nets in Base 3

(169−81, 169, 69)-Net over F₃ — Constructive and digital

Digital (88, 169, 69)-net over F₃, using

(u,Â u+v)-construction [i] based on
1. digital (21, 61, 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, 108, 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]

(169−81, 169, 98)-Net over F₃ — Digital

Digital (88, 169, 98)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(169−81, 169, 756)-Net in Base 3 — Upper bound on s

There is no (88, 169, 757)-net in base 3, because

1 times m-reduction [i] would yield (88, 168, 757)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 144 411977 188638 811851 196798 211705 886089 997351 190099 095374 017489 265756 752358 435553 > 3¹⁶⁸ [i]
