Best Known (64, 256, s)-Nets in Base 2

(64, 256, 43)-Net over F₂ — Constructive and digital

Digital (64, 256, 43)-net over F₂, using

t-expansion [i] based on digital (59, 256, 43)-net over F₂, using
- net from sequence [i] based on digital (59, 42)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ III based on the algebraic function field F/F₂ with g(F)Â =Â 54, N(F)Â =Â 42, and 1 place with degree 6 [i] based on function field F/F₂ with g(F) = 54 and N(F) ≥ 42, using an explicitly constructive algebraic function field [i]

(64, 256, 44)-Net over F₂ — Digital

Digital (64, 256, 44)-net over F₂, using

t-expansion [i] based on digital (62, 256, 44)-net over F₂, using
- net from sequence [i] based on digital (62, 43)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 62 and N(F) ≥ 44, using
    - a function field from a table by Niederreiter and Xing [i]

(64, 256, 81)-Net in Base 2 — Upper bound on s

There is no (64, 256, 82)-net in base 2, because

18 times m-reduction [i] would yield (64, 238, 82)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2²³⁸, 82, S₂, 3, 174), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 84 808659 109362 447819 998280 035660 088759 719227 050029 709989 837097 662045 749248 / 175 > 2²³⁸ [i]
