(20, 20+37, 213832)-Net in Base 128 — Upper bound on s
There is no (20, 57, 213833)-net in base 128, because
- 1 times m-reduction [i] would yield (20, 56, 213833)-net in base 128, but
- the generalized Rao bound for nets shows that 128m ≥ 10087 580050 679861 507622 179083 251184 725619 848376 648496 235843 222516 059337 486523 837016 071234 766304 481747 326345 081139 668496 > 12856 [i]
