Best Known (21, 21+22, s)-Nets in Base 16
(21, 21+22, 257)-Net over F16 — Constructive and digital
Digital (21, 43, 257)-net over F16, using
- base reduction for projective spaces (embedding PG(21,256) in PG(42,16)) for nets [i] based on digital (0, 22, 257)-net over F256, using
- net from sequence [i] based on digital (0, 256)-sequence over F256, using
- generalized Faure sequence [i]
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F256 with g(F) = 0 and N(F) ≥ 257, using
- the rational function field F256(x) [i]
- Niederreiter sequence [i]
- net from sequence [i] based on digital (0, 256)-sequence over F256, using
(21, 21+22, 16664)-Net in Base 16 — Upper bound on s
There is no (21, 43, 16665)-net in base 16, because
- the generalized Rao bound for nets shows that 16m ≥ 5988 936776 644431 145692 331892 378435 423992 540349 940976 > 1643 [i]
