Best Known (31−7, 31, s)-Nets in Base 2
(31−7, 31, 510)-Net over F2 — Constructive and digital
Digital (24, 31, 510)-net over F2, using
- 22 times duplication [i] based on digital (22, 29, 510)-net over F2, using
- net defined by OOA [i] based on linear OOA(229, 510, F2, 7, 7) (dual of [(510, 7), 3541, 8]-NRT-code), using
- OOA stacking with additional row [i] based on linear OOA(229, 511, F2, 3, 7) (dual of [(511, 3), 1504, 8]-NRT-code), using
- net defined by OOA [i] based on linear OOA(229, 510, F2, 7, 7) (dual of [(510, 7), 3541, 8]-NRT-code), using
(31−7, 31, 511)-Net over F2 — Digital
Digital (24, 31, 511)-net over F2, using
- 22 times duplication [i] based on digital (22, 29, 511)-net over F2, using
- net defined by OOA [i] based on linear OOA(229, 511, F2, 7, 7) (dual of [(511, 7), 3548, 8]-NRT-code), using

- embedding of OOA with Gilbert–Varšamov bound [i] based on linear OOA(229, 511, F2, 3, 7) (dual of [(511, 3), 1504, 8]-NRT-code), using
- appending kth column [i] based on linear OOA(229, 511, F2, 6, 7) (dual of [(511, 6), 3037, 8]-NRT-code), using
- net defined by OOA [i] based on linear OOA(229, 511, F2, 7, 7) (dual of [(511, 7), 3548, 8]-NRT-code), using
(31−7, 31, 1856)-Net in Base 2 — Upper bound on s
There is no (24, 31, 1857)-net in base 2, because
- 1 times m-reduction [i] would yield (24, 30, 1857)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 1074 200840 > 230 [i]
