Best Known (220−135, 220, s)-Nets in Base 2
(220−135, 220, 52)-Net over F2 — Constructive and digital
Digital (85, 220, 52)-net over F2, using

(220−135, 220, 163)-Net in Base 2 — Upper bound on s
There is no (85, 220, 164)-net in base 2, because
- 1 times m-reduction [i] would yield (85, 219, 164)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 915284 780894 787753 415116 614258 379977 598334 534644 862293 307759 113486 > 2219 [i]
