(170, 170+35, 29372)-Net in Base 2 — Upper bound on s
There is no (170, 205, 29373)-net in base 2, because
- 1 times m-reduction [i] would yield (170, 204, 29373)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 25 723580 262600 490405 094497 311764 891500 428663 100515 066805 537478 > 2204 [i]
