MinT - Best Known (219−73, 219, s)-Nets in Base 2

Best Known (219−73, 219, s)-Nets in Base 2

(219−73, 219, 112)-Net over F₂ — Constructive and digital

Digital (146, 219, 112)-net over F₂, using

7 times m-reduction [i] based on digital (146, 226, 112)-net over F₂, using
- trace code for nets [i] based on digital (33, 113, 56)-net over F₄, using
  - net from sequence [i] based on digital (33, 55)-sequence over F₄, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 33 and N(F) ≥ 56, using
      - F₅ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(219−73, 219, 151)-Net over F₂ — Digital

Digital (146, 219, 151)-net over F₂, using

Gilbertâ€“VarÅ¡amov bound [i]

(219−73, 219, 897)-Net in Base 2 — Upper bound on s

There is no (146, 219, 898)-net in base 2, because

1 times m-reduction [i] would yield (146, 218, 898)-net in base 2, but
- the generalized Rao bound for nets shows that 2^mÂ â‰¥ 426757 216991 424671 206267 397537 228181 541564 547063 220790 203823 537888 > 2²¹⁸ [i]
