Best Known (18, 18+87, s)-Nets in Base 9
(18, 18+87, 74)-Net over F9 — Constructive and digital
Digital (18, 105, 74)-net over F9, using
- t-expansion [i] based on digital (17, 105, 74)-net over F9, using
- net from sequence [i] based on digital (17, 73)-sequence over F9, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F9 with g(F) = 17 and N(F) ≥ 74, using
- net from sequence [i] based on digital (17, 73)-sequence over F9, using
(18, 18+87, 402)-Net in Base 9 — Upper bound on s
There is no (18, 105, 403)-net in base 9, because
- 1 times m-reduction [i] would yield (18, 104, 403)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 1751 838828 250573 360011 122848 668025 590659 256406 812513 776242 049727 768427 407953 009090 654230 485250 960905 > 9104 [i]
