(46, 65, 1565399)-Net in Base 8 — Upper bound on s
There is no (46, 65, 1565400)-net in base 8, because
- 1 times m-reduction [i] would yield (46, 64, 1565400)-net in base 8, but
- the generalized Rao bound for nets shows that 8m ≥ 6277 120857 409275 648785 898545 627460 691750 640127 730650 868786 > 864 [i]
