(103, 132, 866746)-Net in Base 4 — Upper bound on s
There is no (103, 132, 866747)-net in base 4, because
- 1 times m-reduction [i] would yield (103, 131, 866747)-net in base 4, but
- the generalized Rao bound for nets shows that 4m ≥ 7 410720 022441 012409 868653 912082 305183 219250 611921 687417 919775 362665 701391 386204 > 4131 [i]
