(37, 37+19, 195670)-Net in Base 8 — Upper bound on s
There is no (37, 56, 195671)-net in base 8, because
- 1 times m-reduction [i] would yield (37, 55, 195671)-net in base 8, but
- the generalized Rao bound for nets shows that 8m ≥ 46 769539 206473 884903 205940 519446 670736 500149 005556 > 855 [i]
