MinT - Best Known (220−203, 220, s)-Nets in Base 2

Best Known (220−203, 220, s)-Nets in Base 2

(220−203, 220, 17)-Net over F₂ — Constructive and digital

Digital (17, 220, 17)-net over F₂, using

t-expansion [i] based on digital (15, 220, 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]

(220−203, 220, 24)-Net in Base 2 — Upper bound on s

There is no (17, 220, 25)-net in base 2, because

126 times m-reduction [i] would yield (17, 94, 25)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2⁹⁴, 25, S₂, 4, 77), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 911123 868914 039882 325755 428864 / 39 > 2⁹⁴ [i]
