Best Known (221−57, 221, s)-Nets in Base 3

(221−57, 221, 288)-Net over F₃ — Constructive and digital

Digital (164, 221, 288)-net over F₃, using

t-expansion [i] based on digital (163, 221, 288)-net over F₃, using
- 7 times m-reduction [i] based on digital (163, 228, 288)-net over F₃, using
  - trace code for nets [i] based on digital (11, 76, 96)-net over F₂₇, using
    - net from sequence [i] based on digital (11, 95)-sequence over F₂₇, using
      - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₂₇ with g(F) = 11 and N(F) ≥ 96, using
        an explicitly constructive algebraic function field [i]

(221−57, 221, 818)-Net over F₃ — Digital

Digital (164, 221, 818)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(221−57, 221, 31652)-Net in Base 3 — Upper bound on s

There is no (164, 221, 31653)-net in base 3, because

1 times m-reduction [i] would yield (164, 220, 31653)-net in base 3, but
- the generalized Rao bound for nets shows that 3^mÂ â‰¥ 926 556679 559007 565989 941893 036451 930827 848991 719195 321835 276965 655896 681040 622241 466183 678380 840204 555505 > 3²²⁰ [i]
