Best Known (37, 37+68, s)-Nets in Base 3

(37, 37+68, 38)-Net over F₃ — Constructive and digital

Digital (37, 105, 38)-net over F₃, using

t-expansion [i] based on digital (32, 105, 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]

(37, 37+68, 52)-Net over F₃ — Digital

Digital (37, 105, 52)-net over F₃, using

net from sequence [i] based on digital (37, 51)-sequence over F₃, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 37 and N(F) ≥ 52, using
  - a curve from the manYPoints database [i]

(37, 37+68, 121)-Net in Base 3 — Upper bound on s

There is no (37, 105, 122)-net in base 3, because

extracting embedded orthogonal array [i] would yield OA(3¹⁰⁵, 122, S₃, 68), but
- the linear programming bound shows that MÂ â‰¥ 41138 964191 045188 574191 437825 357748 296404 110765 403562 571641 / 318 455033 > 3¹⁰⁵ [i]
