Best Known (91, 91+112, s)-Nets in Base 2

(91, 91+112, 53)-Net over F₂ — Constructive and digital

Digital (91, 203, 53)-net over F₂, using

t-expansion [i] based on digital (90, 203, 53)-net over F₂, using
- net from sequence [i] based on digital (90, 52)-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 4 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]

(91, 91+112, 57)-Net over F₂ — Digital

Digital (91, 203, 57)-net over F₂, using

t-expansion [i] based on digital (83, 203, 57)-net over F₂, using
- net from sequence [i] based on digital (83, 56)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 83 and N(F) ≥ 57, using
    - an algebraic function field by Auer [i]

(91, 91+112, 192)-Net over F₂ — Upper bound on s (digital)

There is no digital (91, 203, 193)-net over F₂, because

16 times m-reduction [i] would yield digital (91, 187, 193)-net over F₂, but
- extracting embedded orthogonal array [i] would yield linear OA(2¹⁸⁷, 193, F₂, 96) (dual of [193, 6, 97]-code), but
  - 1 times code embedding in larger space [i] would yield linear OA(2¹⁸⁸, 194, F₂, 96) (dual of [194, 6, 97]-code), but
    - Griesmer bound [i]

(91, 91+112, 194)-Net in Base 2 — Upper bound on s

There is no (91, 203, 195)-net in base 2, because

the generalized Rao bound for nets shows that 2^mÂ â‰¥ 14 164231 622930 533450 013818 103051 854216 621415 943526 713794 884520 > 2²⁰³ [i]
