(80, 80+27, 708980)-Net in Base 5 — Upper bound on s
There is no (80, 107, 708981)-net in base 5, because
- 1 times m-reduction [i] would yield (80, 106, 708981)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 123 260233 831215 366616 877920 111475 580585 082811 597827 883973 374781 481085 722725 > 5106 [i]
