MinT - Best Known (163−133, 163, s)-Nets in Base 2

Best Known (163−133, 163, s)-Nets in Base 2

(163−133, 163, 21)-Net over F₂ — Constructive and digital

Digital (30, 163, 21)-net over F₂, using

t-expansion [i] based on digital (21, 163, 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]

(163−133, 163, 25)-Net over F₂ — Digital

Digital (30, 163, 25)-net over F₂, using

t-expansion [i] based on digital (28, 163, 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]

(163−133, 163, 39)-Net in Base 2 — Upper bound on s

There is no (30, 163, 40)-net in base 2, because

12 times m-reduction [i] would yield (30, 151, 40)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2¹⁵¹, 40, S₂, 4, 121), but
  - the LP bound with quadratic polynomials shows that MÂ â‰¥ 176265 090049 186045 310698 317227 012649 343269 208064 / 61 > 2¹⁵¹ [i]
