Best Known (67−42, 67, s)-Nets in Base 3

(67−42, 67, 32)-Net over F₃ — Constructive and digital

Digital (25, 67, 32)-net over F₃, using

t-expansion [i] based on digital (21, 67, 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]

(67−42, 67, 36)-Net over F₃ — Digital

Digital (25, 67, 36)-net over F₃, using

net from sequence [i] based on digital (25, 35)-sequence over F₃, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 25 and N(F) ≥ 36, using
  - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(67−42, 67, 103)-Net in Base 3 — Upper bound on s

There is no (25, 67, 104)-net in base 3, because

extracting embedded orthogonal array [i] would yield OA(3⁶⁷, 104, S₃, 42), but
- the linear programming bound shows that MÂ â‰¥ 212 605728 850688 050166 936203 491470 637703 282614 368879 086023 / 2 198444 497742 188955 528500 > 3⁶⁷ [i]
