MinT - Best Known (18, 18+23, s)-Nets in Base 3

Best Known (18, 18+23, s)-Nets in Base 3

(18, 18+23, 28)-Net over F₃ — Constructive and digital

Digital (18, 41, 28)-net over F₃, using

t-expansion [i] based on digital (15, 41, 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+23, 123)-Net in Base 3 — Upper bound on s

There is no (18, 41, 124)-net in base 3, because

1 times m-reduction [i] would yield (18, 40, 124)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 13 011252 181783 621329 > 3⁴⁰ [i]
