MinT - Best Known (122−80, 122, s)-Nets in Base 3

Best Known (122−80, 122, s)-Nets in Base 3

(122−80, 122, 42)-Net over F₃ — Constructive and digital

Digital (42, 122, 42)-net over F₃, using

t-expansion [i] based on digital (39, 122, 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]

(122−80, 122, 56)-Net over F₃ — Digital

Digital (42, 122, 56)-net over F₃, using

t-expansion [i] based on digital (40, 122, 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
    - a curve from the manYPoints database [i]

(122−80, 122, 134)-Net in Base 3 — Upper bound on s

There is no (42, 122, 135)-net in base 3, because

extracting embedded orthogonal array [i] would yield OA(3¹²², 135, S₃, 80), but
- the linear programming bound shows that MÂ â‰¥ 1 310020 508637 620352 391208 095712 502073 964245 732475 093456 566329 / 65 > 3¹²² [i]
