Best Known (72−43, 72, s)-Nets in Base 2

(72−43, 72, 21)-Net over F₂ — Constructive and digital

Digital (29, 72, 21)-net over F₂, using

t-expansion [i] based on digital (21, 72, 21)-net over F₂, using
- net from sequence [i] based on digital (21, 20)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 21 and N(F) ≥ 21, using
    - an explicitly constructive algebraic function field [i]

(72−43, 72, 25)-Net over F₂ — Digital

Digital (29, 72, 25)-net over F₂, using

t-expansion [i] based on digital (28, 72, 25)-net over F₂, using
- net from sequence [i] based on digital (28, 24)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 28 and N(F) ≥ 25, using
    - a curve from the manYPoints database [i]

(72−43, 72, 63)-Net in Base 2 — Upper bound on s

There is no (29, 72, 64)-net in base 2, because

1 times m-reduction [i] would yield (29, 71, 64)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 2647 275124 346222 499685 > 2⁷¹ [i]
