(140, 140+43, 477759)-Net in Base 4 — Upper bound on s
There is no (140, 183, 477760)-net in base 4, because
- 1 times m-reduction [i] would yield (140, 182, 477760)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 37 577895 569271 013731 743376 884547 978585 229498 568005 492635 003975 443991 847133 227274 226446 409278 104609 385914 820869 > 4182 [i]
