MinT - Best Known (141−122, 141, s)-Nets in Base 3

Best Known (141−122, 141, s)-Nets in Base 3

(141−122, 141, 28)-Net over F₃ — Constructive and digital

Digital (19, 141, 28)-net over F₃, using

t-expansion [i] based on digital (15, 141, 28)-net over F₃, using
- net from sequence [i] based on digital (15, 27)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 15 and N(F) ≥ 28, using
    - an explicitly constructive algebraic function field [i]

(141−122, 141, 32)-Net over F₃ — Digital

Digital (19, 141, 32)-net over F₃, using

net from sequence [i] based on digital (19, 31)-sequence over F₃, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 19 and N(F) ≥ 32, using
  - a curve from the manYPoints database [i]

(141−122, 141, 51)-Net in Base 3 — Upper bound on s

There is no (19, 141, 52)-net in base 3, because

41 times m-reduction [i] would yield (19, 100, 52)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(3¹⁰⁰, 52, S₃, 2, 81), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 23 191988 432940 509896 640750 839452 957271 594838 490045 / 41 > 3¹⁰⁰ [i]
