There is no (139, 182, 447238)-net in base 4, because
- 1 times m-reduction [i] would yield (139, 181, 447238)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 9 394241 582722 641980 466717 650958 434262 481117 336471 660623 005501 851883 120680 572895 733767 238190 805091 076140 617840 > 4181 [i]
