Best Known (31−21, 31, s)-Nets in Base 4
(31−21, 31, 27)-Net over F4 — Constructive and digital
Digital (10, 31, 27)-net over F4, using
- net from sequence [i] based on digital (10, 26)-sequence over F4, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F4 with g(F) = 10 and N(F) ≥ 27, using
(31−21, 31, 89)-Net in Base 4 — Upper bound on s
There is no (10, 31, 90)-net in base 4, because
- 1 times m-reduction [i] would yield (10, 30, 90)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 1 275618 604557 474928 > 430 [i]
