Best Known (87−55, 87, s)-Nets in Base 3

(87−55, 87, 38)-Net over F₃ — Constructive and digital

Digital (32, 87, 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]

(87−55, 87, 42)-Net over F₃ — Digital

Digital (32, 87, 42)-net over F₃, using

t-expansion [i] based on digital (29, 87, 42)-net over F₃, using
- net from sequence [i] based on digital (29, 41)-sequence over F₃, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₃ with g(F) = 29 and N(F) ≥ 42, using
    - algebraic function fields over â„¤₃ by Niederreiter/Xing [i]

(87−55, 87, 115)-Net in Base 3 — Upper bound on s

There is no (32, 87, 116)-net in base 3, because

extracting embedded orthogonal array [i] would yield OA(3⁸⁷, 116, S₃, 55), but
- the linear programming bound shows that MÂ â‰¥ 19 951398 173459 289781 361021 584173 813598 719799 515314 634201 / 50 708279 529950 > 3⁸⁷ [i]
