(199−37, 199, 15442)-Net in Base 2 — Upper bound on s
There is no (162, 199, 15443)-net in base 2, because
- 1 times m-reduction [i] would yield (162, 198, 15443)-net in base 2, but
- the generalized Rao bound for nets shows that 2m ≥ 401995 819674 680550 870765 537996 929696 831135 839885 819900 060009 > 2198 [i]
