MinT - Best Known (246−121, 246, s)-Nets in Base 3

Best Known (246−121, 246, s)-Nets in Base 3

(246−121, 246, 78)-Net over F₃ — Constructive and digital

Digital (125, 246, 78)-net over F₃, using

t-expansion [i] based on digital (121, 246, 78)-net over F₃, using
- net from sequence [i] based on digital (121, 77)-sequence over F₃, using
  - base reduction for sequences [i] based on digital (22, 77)-sequence over F₉, using
    - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₉ with g(F) = 22 and N(F) ≥ 78, using
      - F₃ from the tower of function fields by GarcÃa and Stichtenoth over F₉ [i]

(246−121, 246, 126)-Net over F₃ — Digital

Digital (125, 246, 126)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(246−121, 246, 971)-Net in Base 3 — Upper bound on s

There is no (125, 246, 972)-net in base 3, because

1 times m-reduction [i] would yield (125, 245, 972)-net in base 3, but
