MinT - Best Known (176−140, 176, s)-Nets in Base 2

Best Known (176−140, 176, s)-Nets in Base 2

(176−140, 176, 24)-Net over F₂ — Constructive and digital

Digital (36, 176, 24)-net over F₂, using

t-expansion [i] based on digital (33, 176, 24)-net over F₂, using
- net from sequence [i] based on digital (33, 23)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 33 and N(F) ≥ 24, using
    - a function field by SÃ©mirat [i]

(176−140, 176, 30)-Net over F₂ — Digital

Digital (36, 176, 30)-net over F₂, using

net from sequence [i] based on digital (36, 29)-sequence over F₂, using
- Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 36 and N(F) ≥ 30, using
  - Drinfeld modules of rank 1 [i]

(176−140, 176, 48)-Net in Base 2 — Upper bound on s

There is no (36, 176, 49)-net in base 2, because

36 times m-reduction [i] would yield (36, 140, 49)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2¹⁴⁰, 49, S₂, 3, 104), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 22 300745 198530 623141 535718 272648 361505 980416 / 15 > 2¹⁴⁰ [i]
