(32, 67, 161467)-Net in Base 32 — Upper bound on s
There is no (32, 67, 161468)-net in base 32, because
- 1 times m-reduction [i] would yield (32, 66, 161468)-net in base 32, but
- the generalized Rao bound for nets shows that 32m ≥ 2187 464710 558848 145134 443641 030402 086836 235095 599612 954594 283191 834474 520604 410696 800270 495957 149949 > 3266 [i]
