Best Known (21−7, 21, s)-Nets in Base 2
(21−7, 21, 64)-Net over F2 — Constructive and digital
Digital (14, 21, 64)-net over F2, using
(21−7, 21, 180)-Net in Base 2 — Upper bound on s
There is no (14, 21, 181)-net in base 2, because
- 1 times m-reduction [i] would yield (14, 20, 181)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1 054688 > 220 [i]
