(137−39, 137, 199654)-Net in Base 5 — Upper bound on s
There is no (98, 137, 199655)-net in base 5, because
- 1 times m-reduction [i] would yield (98, 136, 199655)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 114798 729783 634794 300399 319491 583843 618880 860077 112238 843701 746757 866701 004022 092694 980744 183765 > 5136 [i]
