MinT - Best Known (239−223, 239, s)-Nets in Base 2

Best Known (239−223, 239, s)-Nets in Base 2

(239−223, 239, 17)-Net over F₂ — Constructive and digital

Digital (16, 239, 17)-net over F₂, using

t-expansion [i] based on digital (15, 239, 17)-net over F₂, using
- net from sequence [i] based on digital (15, 16)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 15 and N(F) ≥ 17, using
    - an explicitly constructive algebraic function field [i]

(239−223, 239, 23)-Net in Base 2 — Upper bound on s

There is no (16, 239, 24)-net in base 2, because

149 times m-reduction [i] would yield (16, 90, 24)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2⁹⁰, 24, S₂, 4, 74), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 39614 081257 132168 796771 975168 / 25 > 2⁹⁰ [i]
