Best Known (40, 107, s)-Nets in Base 3

(40, 107, 42)-Net over F₃ — Constructive and digital

Digital (40, 107, 42)-net over F₃, using

t-expansion [i] based on digital (39, 107, 42)-net over F₃, using
- net from sequence [i] based on digital (39, 41)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 39 and N(F) ≥ 42, using
    - an explicitly constructive algebraic function field [i]

(40, 107, 56)-Net over F₃ — Digital

Digital (40, 107, 56)-net over F₃, using

net from sequence [i] based on digital (40, 55)-sequence over F₃, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 40 and N(F) ≥ 56, using

(40, 107, 139)-Net in Base 3 — Upper bound on s

There is no (40, 107, 140)-net in base 3, because

extracting embedded orthogonal array [i] would yield OA(3¹⁰⁷, 140, S₃, 67), but
- the linear programming bound shows that MÂ â‰¥ 844525 880100 396986 903447 529365 331301 813453 462155 135479 667135 368455 815363 / 666 674951 919471 110000 > 3¹⁰⁷ [i]
