Best Known (27, 27+42, s)-Nets in Base 2

(27, 27+42, 21)-Net over F₂ — Constructive and digital

Digital (27, 69, 21)-net over F₂, using

t-expansion [i] based on digital (21, 69, 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]

(27, 27+42, 24)-Net over F₂ — Digital

Digital (27, 69, 24)-net over F₂, using

t-expansion [i] based on digital (25, 69, 24)-net over F₂, using
- net from sequence [i] based on digital (25, 23)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 25 and N(F) ≥ 24, using
    - Drinfeld modules of rank 1 [i]

(27, 27+42, 57)-Net in Base 2 — Upper bound on s

There is no (27, 69, 58)-net in base 2, because

the generalized Rao bound for nets shows that 2^mÂ â‰¥ 592 073439 807649 273242 > 2⁶⁹ [i]
