MinT - Best Known (247−145, 247, s)-Nets in Base 2

Best Known (247−145, 247, s)-Nets in Base 2

(247−145, 247, 55)-Net over F₂ — Constructive and digital

Digital (102, 247, 55)-net over F₂, using

t-expansion [i] based on digital (100, 247, 55)-net over F₂, using
- net from sequence [i] based on digital (100, 54)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 69, N(F)Â =Â 48, 1 place with degree 2, and 6 places with degree 6 [i] based on function field F/F₂ with g(F) = 69 and N(F) ≥ 48, using an explicitly constructive algebraic function field [i]

(247−145, 247, 65)-Net over F₂ — Digital

Digital (102, 247, 65)-net over F₂, using

t-expansion [i] based on digital (95, 247, 65)-net over F₂, using
- net from sequence [i] based on digital (95, 64)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 95 and N(F) ≥ 65, using

(247−145, 247, 202)-Net in Base 2 — Upper bound on s

There is no (102, 247, 203)-net in base 2, because

1 times m-reduction [i] would yield (102, 246, 203)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 123 604900 534617 532220 472132 282624 505297 773251 071566 307941 138603 921148 184467 > 2²⁴⁶ [i]
