Best Known (245−147, 245, s)-Nets in Base 2

(245−147, 245, 54)-Net over F₂ — Constructive and digital

Digital (98, 245, 54)-net over F₂, using

t-expansion [i] based on digital (95, 245, 54)-net over F₂, using
- net from sequence [i] based on digital (95, 53)-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 5 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]

(245−147, 245, 65)-Net over F₂ — Digital

Digital (98, 245, 65)-net over F₂, using

t-expansion [i] based on digital (95, 245, 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

(245−147, 245, 191)-Net in Base 2 — Upper bound on s

There is no (98, 245, 192)-net in base 2, because

1 times m-reduction [i] would yield (98, 244, 192)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 36 949771 816807 497383 637625 693120 750786 999843 145255 591343 914662 994966 612090 > 2²⁴⁴ [i]
