(117−27, 117, 2445162)-Net in Base 5 — Upper bound on s
There is no (90, 117, 2445163)-net in base 5, because
- 1 times m-reduction [i] would yield (90, 116, 2445163)-net in base 5, but
- the generalized Rao bound for nets shows that 5m ≥ 1203 711832 960782 099252 618354 715957 583126 226775 078376 430932 078380 899301 789875 216765 > 5116 [i]
