Best Known (181, 181+5, s)-Nets in Base 2

(181, 181+5, large)-Net over F₂ — Constructive and digital

Digital (181, 186, large)-net over F₂, using

t-expansion [i] based on digital (180, 186, large)-net over F₂, using
- 4 times m-reduction [i] based on digital (180, 190, large)-net over F₂, using
  - (u,Â u+v)-construction [i] based on
    1. digital (41, 46, 4194305)-net over F₂, using
      - nets constructed from net-embeddable BCH codes [i]
    2. digital (134, 144, 4194304)-net over F₂, using
      - (u,Â u+v)-construction [i] based on
        digital (0, 5, 3)-net over F₂, using
        net from sequence [i] based on digital (0, 2)-sequence over F₂, using
        Faure sequence [i]
        Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂ with g(F) = 0 and N(F) ≥ 3, using
        the rational function field F₂(x) [i]
        Niederreiter sequence [i]
        Sobol sequence [i]
        digital (129, 139, 4194301)-net over F₂, using
        1 times m-reduction [i] based on digital (129, 140, 4194301)-net over F₂, using
        net defined by OOA [i] based on linear OOA(2¹⁴⁰, 4194301, F₂, 15, 11) (dual of [(4194301, 15), 62914375, 12]-NRT-code), using
        OOA 2-folding and stacking with additional row [i] based on linear OOA(2¹⁴⁰, large, F₂, 3, 11), using
        OOAs constructed from BCH codes [i]

(181, 181+5, large)-Net in Base 2 — Upper bound on s

There is no (181, 186, large)-net in base 2, because

3 times m-reduction [i] would yield (181, 183, large)-net in base 2, but
- mutually orthogonal hypercube bound [i]
