MinT - Best Known (18, 18+26, s)-Nets in Base 3

Best Known (18, 18+26, s)-Nets in Base 3

(18, 18+26, 28)-Net over F₃ — Constructive and digital

Digital (18, 44, 28)-net over F₃, using

t-expansion [i] based on digital (15, 44, 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]

(18, 18+26, 104)-Net in Base 3 — Upper bound on s

There is no (18, 44, 105)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1009 289861 381099 992739 > 3⁴⁴ [i]
