MinT - Best Known (200−134, 200, s)-Nets in Base 3

Best Known (200−134, 200, s)-Nets in Base 3

(200−134, 200, 48)-Net over F₃ — Constructive and digital

Digital (66, 200, 48)-net over F₃, using

t-expansion [i] based on digital (45, 200, 48)-net over F₃, using
- net from sequence [i] based on digital (45, 47)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 45 and N(F) ≥ 48, using
    - an explicitly constructive algebraic function field [i]

(200−134, 200, 64)-Net over F₃ — Digital

Digital (66, 200, 64)-net over F₃, using

t-expansion [i] based on digital (49, 200, 64)-net over F₃, using
- net from sequence [i] based on digital (49, 63)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 49 and N(F) ≥ 64, using
    - a curve from the manYPoints database [i]

(200−134, 200, 209)-Net over F₃ — Upper bound on s (digital)

There is no digital (66, 200, 210)-net over F₃, because

2 times m-reduction [i] would yield digital (66, 198, 210)-net over F₃, but
- extracting embedded orthogonal array [i] would yield linear OA(3¹⁹⁸, 210, F₃, 132) (dual of [210, 12, 133]-code), but
  - residual code [i] would yield OA(3⁶⁶, 77, S₃, 44), but
    - the linear programming bound shows that MÂ â‰¥ 34 245670 463812 538347 598340 341640 500169 / 1 016275 > 3⁶⁶ [i]

(200−134, 200, 280)-Net in Base 3 — Upper bound on s

There is no (66, 200, 281)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 275640 491943 162744 714236 352677 857889 580333 578854 420588 671642 898395 558397 014566 560418 396536 000059 > 3²⁰⁰ [i]
