MinT - Best Known (234−153, 234, s)-Nets in Base 2

Best Known (234−153, 234, s)-Nets in Base 2

(234−153, 234, 51)-Net over F₂ — Constructive and digital

Digital (81, 234, 51)-net over F₂, using

t-expansion [i] based on digital (80, 234, 51)-net over F₂, using
- net from sequence [i] based on digital (80, 50)-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 2 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]

(234−153, 234, 56)-Net over F₂ — Digital

Digital (81, 234, 56)-net over F₂, using

t-expansion [i] based on digital (80, 234, 56)-net over F₂, using
- net from sequence [i] based on digital (80, 55)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 80 and N(F) ≥ 56, using
    - Drinfeld modules of rank 1 [i]

(234−153, 234, 117)-Net in Base 2 — Upper bound on s

There is no (81, 234, 118)-net in base 2, because

5 times m-reduction [i] would yield (81, 229, 118)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2²²⁹, 118, S₂, 2, 148), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 165641 912322 973530 898434 140694 648610 858826 615332 089277 323900 581371 183104 / 149 > 2²²⁹ [i]
