MinT - Best Known (236−154, 236, s)-Nets in Base 2

Best Known (236−154, 236, s)-Nets in Base 2

(236−154, 236, 51)-Net over F₂ — Constructive and digital

Digital (82, 236, 51)-net over F₂, using

t-expansion [i] based on digital (80, 236, 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]

(236−154, 236, 56)-Net over F₂ — Digital

Digital (82, 236, 56)-net over F₂, using

t-expansion [i] based on digital (80, 236, 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]

(236−154, 236, 118)-Net in Base 2 — Upper bound on s

There is no (82, 236, 119)-net in base 2, because

5 times m-reduction [i] would yield (82, 231, 119)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2²³¹, 119, S₂, 2, 149), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 55213 970774 324510 299478 046898 216203 619608 871777 363092 441300 193790 394368 / 15 > 2²³¹ [i]
