Best Known (154−96, 154, s)-Nets in Base 3

(154−96, 154, 48)-Net over F₃ — Constructive and digital

Digital (58, 154, 48)-net over F₃, using

t-expansion [i] based on digital (45, 154, 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]

(154−96, 154, 64)-Net over F₃ — Digital

Digital (58, 154, 64)-net over F₃, using

t-expansion [i] based on digital (49, 154, 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]

(154−96, 154, 269)-Net over F₃ — Upper bound on s (digital)

There is no digital (58, 154, 270)-net over F₃, because

extracting embedded orthogonal array [i] would yield linear OA(3¹⁵⁴, 270, F₃, 96) (dual of [270, 116, 97]-code), but
- residual code [i] would yield OA(3⁵⁸, 173, S₃, 32), but
  - the linear programming bound shows that MÂ â‰¥ 47 314229 835710 776345 670615 418214 790563 428291 670976 086718 521800 / 9965 095822 320687 546955 148607 190123 > 3⁵⁸ [i]

(154−96, 154, 273)-Net in Base 3 — Upper bound on s

There is no (58, 154, 274)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 33 291403 493062 955455 031318 808964 628689 983340 806207 465632 124879 514764 829665 > 3¹⁵⁴ [i]
