MinT - Best Known (108, 108+87, s)-Nets in Base 4

Best Known (108, 108+87, s)-Nets in Base 4

(108, 108+87, 130)-Net over F₄ — Constructive and digital

Digital (108, 195, 130)-net over F₄, using

t-expansion [i] based on digital (105, 195, 130)-net over F₄, using
- net from sequence [i] based on digital (105, 129)-sequence over F₄, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₄ with g(F) = 105 and N(F) ≥ 130, using
    - T₇ from the second tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(108, 108+87, 201)-Net over F₄ — Digital

Digital (108, 195, 201)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(108, 108+87, 2893)-Net in Base 4 — Upper bound on s

There is no (108, 195, 2894)-net in base 4, because

1 times m-reduction [i] would yield (108, 194, 2894)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 638 397303 843246 477195 915902 749447 684274 104702 233638 887615 401714 318578 639021 026346 999793 989262 645006 871712 961868 774156 > 4¹⁹⁴ [i]
