Best Known (12, 12+27, s)-Nets in Base 7
(12, 12+27, 20)-Net over F7 — Constructive and digital
Digital (12, 39, 20)-net over F7, using
- net from sequence [i] based on digital (12, 19)-sequence over F7, using
(12, 12+27, 38)-Net over F7 — Digital
Digital (12, 39, 38)-net over F7, using
- t-expansion [i] based on digital (9, 39, 38)-net over F7, using
- net from sequence [i] based on digital (9, 37)-sequence over F7, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F7 with g(F) = 9 and N(F) ≥ 38, using

(12, 12+27, 270)-Net in Base 7 — Upper bound on s
There is no (12, 39, 271)-net in base 7, because
- 1 times m-reduction [i] would yield (12, 38, 271)-net in base 7, but
- the generalized Rao bound for nets shows that 7m ≥ 130 714727 125390 670967 274337 023123 > 738 [i]
