(62, 83, 610190)-Net in Base 5 — Upper bound on s
There is no (62, 83, 610191)-net in base 5, because
- 1 times m-reduction [i] would yield (62, 82, 610191)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 2067 972116 894233 791881 245653 869969 248181 309381 010377 198553 > 582 [i]
