MinT - Best Known (139−107, 139, s)-Nets in Base 2

Best Known (139−107, 139, s)-Nets in Base 2

(139−107, 139, 21)-Net over F₂ — Constructive and digital

Digital (32, 139, 21)-net over F₂, using

t-expansion [i] based on digital (21, 139, 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]

(139−107, 139, 27)-Net over F₂ — Digital

Digital (32, 139, 27)-net over F₂, using

t-expansion [i] based on digital (31, 139, 27)-net over F₂, using
- net from sequence [i] based on digital (31, 26)-sequence over F₂, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 31 and N(F) ≥ 27, using
    - Drinfeld modules of rank 1 [i]

(139−107, 139, 43)-Net in Base 2 — Upper bound on s

There is no (32, 139, 44)-net in base 2, because

13 times m-reduction [i] would yield (32, 126, 44)-net in base 2, but
- extracting embedded OOA [i] would yield OOA(2¹²⁶, 44, S₂, 3, 94), but
  - the (dual) Plotkin bound for OOAs shows that MÂ â‰¥ 8166 776806 102523 123120 990578 362437 074944 / 95 > 2¹²⁶ [i]
