(137−31, 137, 615622)-Net in Base 4 — Upper bound on s
There is no (106, 137, 615623)-net in base 4, because
- 1 times m-reduction [i] would yield (106, 136, 615623)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 7588 723746 423574 389692 215702 231121 228667 649113 235377 372888 018090 977038 691820 405856 > 4136 [i]
