MinT - Best Known (20, 49, s)-Nets in Base 2

Best Known (20, 49, s)-Nets in Base 2

(20, 49, 20)-Net over F₂ — Constructive and digital

Digital (20, 49, 20)-net over F₂, using

t-expansion [i] based on digital (19, 49, 20)-net over F₂, using
- net from sequence [i] based on digital (19, 19)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 19 and N(F) ≥ 20, using
    - an explicitly constructive algebraic function field [i]

(20, 49, 47)-Net in Base 2 — Upper bound on s

There is no (20, 49, 48)-net in base 2, because

1 times m-reduction [i] would yield (20, 48, 48)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 342 334020 644939 > 2⁴⁸ [i]
