Best Known (17, 53, s)-Nets in Base 3

(17, 53, 28)-Net over F₃ — Constructive and digital

Digital (17, 53, 28)-net over F₃, using

t-expansion [i] based on digital (15, 53, 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]

(17, 53, 57)-Net over F₃ — Upper bound on s (digital)

There is no digital (17, 53, 58)-net over F₃, because

extracting embedded orthogonal array [i] would yield linear OA(3⁵³, 58, F₃, 36) (dual of [58, 5, 37]-code), but
- residual code [i] would yield linear OA(3¹⁷, 21, F₃, 12) (dual of [21, 4, 13]-code), but
  - â€œHNâ€ bound on codes from Brouwerâ€™s database [i]

(17, 53, 62)-Net in Base 3 — Upper bound on s

There is no (17, 53, 63)-net in base 3, because

1 times m-reduction [i] would yield (17, 52, 63)-net in base 3, but
- extracting embedded orthogonal array [i] would yield OA(3⁵², 63, S₃, 35), but
  - the linear programming bound shows that MÂ â‰¥ 36110 986678 887877 067732 294949 / 4214 > 3⁵² [i]
