(139, 139+45, 307433)-Net in Base 4 — Upper bound on s
There is no (139, 184, 307434)-net in base 4, because
- 1 times m-reduction [i] would yield (139, 183, 307434)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 150 313128 799973 954302 371144 635358 600809 855967 223562 236721 474103 315869 724238 782995 054817 231227 916445 360316 480680 > 4183 [i]
