Best Known (68, 68+123, s)-Nets in Base 2
(68, 68+123, 43)-Net over F2 — Constructive and digital
Digital (68, 191, 43)-net over F2, using
- t-expansion [i] based on digital (59, 191, 43)-net over F2, using
- net from sequence [i] based on digital (59, 42)-sequence over F2, using
- Niederreiter–Xing sequence construction III based on the algebraic function field F/F2 with g(F) = 54, N(F) = 42, and 1 place with degree 6 [i] based on function field F/F2 with g(F) = 54 and N(F) ≥ 42, using an explicitly constructive algebraic function field [i]
- net from sequence [i] based on digital (59, 42)-sequence over F2, using
(68, 68+123, 49)-Net over F2 — Digital
Digital (68, 191, 49)-net over F2, using
- net from sequence [i] based on digital (68, 48)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 68 and N(F) ≥ 49, using
(68, 68+123, 128)-Net in Base 2 — Upper bound on s
There is no (68, 191, 129)-net in base 2, because
- 1 times m-reduction [i] would yield (68, 190, 129)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 2040 314414 519465 281114 708712 302329 957841 630415 041281 103040 > 2190 [i]
