MinT - Best Known (247−141, 247, s)-Nets in Base 2

Best Known (247−141, 247, s)-Nets in Base 2

(247−141, 247, 56)-Net over F₂ — Constructive and digital

Digital (106, 247, 56)-net over F₂, using

t-expansion [i] based on digital (105, 247, 56)-net over F₂, using
- net from sequence [i] based on digital (105, 55)-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 7 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]

(247−141, 247, 65)-Net over F₂ — Digital

Digital (106, 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

(247−141, 247, 216)-Net in Base 2 — Upper bound on s

There is no (106, 247, 217)-net in base 2, because

1 times m-reduction [i] would yield (106, 246, 217)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 124 337866 906381 257850 815372 978361 752944 563725 469455 749186 448535 508768 882548 > 2²⁴⁶ [i]
