(122−27, 122, 78199)-Net in Base 3 — Upper bound on s
There is no (95, 122, 78200)-net in base 3, because
- 1 times m-reduction [i] would yield (95, 121, 78200)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 5391 377608 706109 644792 013392 088107 274302 296080 683778 617841 > 3121 [i]
