(110, 139, 152560)-Net in Base 3 — Upper bound on s
There is no (110, 139, 152561)-net in base 3, because
- 1 times m-reduction [i] would yield (110, 138, 152561)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 696239 955921 931079 939527 157268 840945 865762 591638 704306 125720 521177 > 3138 [i]
