Best Known (21−17, 21, s)-Nets in Base 49
(21−17, 21, 54)-Net over F49 — Constructive and digital
Digital (4, 21, 54)-net over F49, using
- net from sequence [i] based on digital (4, 53)-sequence over F49, using
(21−17, 21, 92)-Net over F49 — Digital
Digital (4, 21, 92)-net over F49, using
- t-expansion [i] based on digital (3, 21, 92)-net over F49, using
- net from sequence [i] based on digital (3, 91)-sequence over F49, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F49 with g(F) = 3 and N(F) ≥ 92, using

(21−17, 21, 1314)-Net in Base 49 — Upper bound on s
There is no (4, 21, 1315)-net in base 49, because
- 1 times m-reduction [i] would yield (4, 20, 1315)-net in base 49, but
- the generalized Rao bound for nets shows that 49m ≥ 6389 739726 804818 048231 406736 301185 > 4920 [i]
