Best Known (27, 27+105, s)-Nets in Base 2

(27, 27+105, 21)-Net over F₂ — Constructive and digital

Digital (27, 132, 21)-net over F₂, using

t-expansion [i] based on digital (21, 132, 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+105, 24)-Net over F₂ — Digital

Digital (27, 132, 24)-net over F₂, using

t-expansion [i] based on digital (25, 132, 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+105, 38)-Net in Base 2 — Upper bound on s

There is no (27, 132, 39)-net in base 2, because

22 times m-reduction [i] would yield (27, 110, 39)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2¹¹⁰, 39, S₂, 3, 83), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 15576 890575 604482 885591 488987 660288 / 7 > 2¹¹⁰ [i]
