Best Known (21, 21+106, s)-Nets in Base 9
(21, 21+106, 74)-Net over F9 — Constructive and digital
Digital (21, 127, 74)-net over F9, using
- t-expansion [i] based on digital (17, 127, 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
(21, 21+106, 88)-Net over F9 — Digital
Digital (21, 127, 88)-net over F9, using
- net from sequence [i] based on digital (21, 87)-sequence over F9, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F9 with g(F) = 21 and N(F) ≥ 88, using
(21, 21+106, 465)-Net in Base 9 — Upper bound on s
There is no (21, 127, 466)-net in base 9, because
- 2 times m-reduction [i] would yield (21, 125, 466)-net in base 9, but
- the generalized Rao bound for nets shows that 9m ≥ 192020 205893 151328 802922 969527 222490 548694 151072 094943 272632 768940 918567 543157 999978 924296 413317 686609 815520 964326 335425 > 9125 [i]
