(75−17, 75, 2748537)-Net in Base 5 — Upper bound on s
There is no (58, 75, 2748538)-net in base 5, because
- 1 times m-reduction [i] would yield (58, 74, 2748538)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 5293 955972 518118 910229 770108 031333 059939 981997 448065 > 574 [i]
