MinT - Best Known (109−85, 109, s)-Nets in Base 2

Best Known (109−85, 109, s)-Nets in Base 2

(109−85, 109, 21)-Net over F₂ — Constructive and digital

Digital (24, 109, 21)-net over F₂, using

t-expansion [i] based on digital (21, 109, 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]

(109−85, 109, 22)-Net over F₂ — Digital

Digital (24, 109, 22)-net over F₂, using

t-expansion [i] based on digital (23, 109, 22)-net over F₂, using
- net from sequence [i] based on digital (23, 21)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 23 and N(F) ≥ 22, using
    - Drinfeld modules of rank 1 [i]

(109−85, 109, 34)-Net in Base 2 — Upper bound on s

There is no (24, 109, 35)-net in base 2, because

11 times m-reduction [i] would yield (24, 98, 35)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2⁹⁸, 35, S₂, 3, 74), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 5 070602 400912 917605 986812 821504 / 15 > 2⁹⁸ [i]
