Best Known (221−141, 221, s)-Nets in Base 2
(221−141, 221, 51)-Net over F2 — Constructive and digital
Digital (80, 221, 51)-net over F2, using
- net from sequence [i] based on digital (80, 50)-sequence over F2, using
- Niederreiter–Xing sequence construction III based on the algebraic function field F/F2 with g(F) = 69, N(F) = 48, 1 place with degree 2, and 2 places with degree 6 [i] based on function field F/F2 with g(F) = 69 and N(F) ≥ 48, using an explicitly constructive algebraic function field [i]
(221−141, 221, 56)-Net over F2 — Digital
Digital (80, 221, 56)-net over F2, using
- net from sequence [i] based on digital (80, 55)-sequence over F2, using
- Niederreiter–Xing sequence construction II/III [i] based on function field F/F2 with g(F) = 80 and N(F) ≥ 56, using
(221−141, 221, 150)-Net in Base 2 — Upper bound on s
There is no (80, 221, 151)-net in base 2, because
- 1 times m-reduction [i] would yield (80, 220, 151)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 2 179110 927913 522277 691306 432319 219234 548840 804658 113437 665376 093838 > 2220 [i]
