Best Known (242−109, 242, s)-Nets in Base 3

(242−109, 242, 86)-Net over F₃ — Constructive and digital

Digital (133, 242, 86)-net over F₃, using

3 times m-reduction [i] based on digital (133, 245, 86)-net over F₃, using
- (u,Â u+v)-construction [i] based on
  1. digital (32, 88, 38)-net over F₃, using
    - net from sequence [i] based on digital (32, 37)-sequence over F₃, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 32 and N(F) ≥ 38, using
        an explicitly constructive algebraic function field [i]
  2. digital (45, 157, 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]

(242−109, 242, 159)-Net over F₃ — Digital

Digital (133, 242, 159)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(242−109, 242, 1359)-Net in Base 3 — Upper bound on s

There is no (133, 242, 1360)-net in base 3, because

1 times m-reduction [i] would yield (133, 241, 1360)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 9 875027 136746 855936 043963 261522 252639 529180 605599 453940 153719 238046 836512 857269 922827 597844 445657 587714 337209 997281 > 3²⁴¹ [i]
