(192−45, 192, 508969)-Net in Base 4 — Upper bound on s
There is no (147, 192, 508970)-net in base 4, because
- 1 times m-reduction [i] would yield (147, 191, 508970)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 9 850626 082446 818558 222806 828636 768394 492343 013169 642729 866615 864517 332256 445293 141425 660654 320445 721231 493702 993304 > 4191 [i]
