MinT - Best Known (215−189, 215, s)-Nets in Base 2

Best Known (215−189, 215, s)-Nets in Base 2

(215−189, 215, 21)-Net over F₂ — Constructive and digital

Digital (26, 215, 21)-net over F₂, using

t-expansion [i] based on digital (21, 215, 21)-net over F₂, using
- net from sequence [i] based on digital (21, 20)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 21 and N(F) ≥ 21, using
    - an explicitly constructive algebraic function field [i]

(215−189, 215, 24)-Net over F₂ — Digital

Digital (26, 215, 24)-net over F₂, using

t-expansion [i] based on digital (25, 215, 24)-net over F₂, using
- net from sequence [i] based on digital (25, 23)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 25 and N(F) ≥ 24, using
    - Drinfeld modules of rank 1 [i]

(215−189, 215, 33)-Net in Base 2 — Upper bound on s

There is no (26, 215, 34)-net in base 2, because

18 times m-reduction [i] would yield (26, 197, 34)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2¹⁹⁷, 34, S₂, 6, 171), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 9 440761 010021 567868 809027 292504 330289 817942 588473 907907 395584 / 43 > 2¹⁹⁷ [i]
