MinT - Best Known (20, 75, s)-Nets in Base 7

Best Known (20, 75, s)-Nets in Base 7

(20, 75, 28)-Net over F₇ — Constructive and digital

Digital (20, 75, 28)-net over F₇, using

net from sequence [i] based on digital (20, 27)-sequence over F₇, using
- Niederreiter sequence [i]

(20, 75, 54)-Net over F₇ — Digital

Digital (20, 75, 54)-net over F₇, using

t-expansion [i] based on digital (19, 75, 54)-net over F₇, using
- net from sequence [i] based on digital (19, 53)-sequence over F₇, using
  - Niederreiterâ€“Xing sequence constructionÂ II/III [i] based on function field F/F₇ with g(F) = 19 and N(F) ≥ 54, using
    - an algebraic function field by Teo [i]

(20, 75, 359)-Net in Base 7 — Upper bound on s

There is no (20, 75, 360)-net in base 7, because

1 times m-reduction [i] would yield (20, 74, 360)-net in base 7, but
- the generalized Rao bound for nets shows that 7^mÂ â‰¥ 348 255343 666428 639944 654583 771649 718290 182833 944019 067816 261121 > 7⁷⁴ [i]
