Best Known (21, 176, s)-Nets in Base 3
(21, 176, 32)-Net over F3 — Constructive and digital
Digital (21, 176, 32)-net over F3, using
- net from sequence [i] based on digital (21, 31)-sequence over F3, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F3 with g(F) = 21 and N(F) ≥ 32, using
(21, 176, 53)-Net in Base 3 — Upper bound on s
There is no (21, 176, 54)-net in base 3, because
- 20 times m-reduction [i] would yield (21, 156, 54)-net in base 3, but
- extracting embedded OOA [i] would yield OOA(3156, 54, S3, 3, 135), but
- the LP bound with quadratic polynomials shows that M ≥ 10159 513810 579551 549539 358785 341138 152716 364863 601403 137991 148585 180705 169291 / 34 > 3156 [i]
- extracting embedded OOA [i] would yield OOA(3156, 54, S3, 3, 135), but
