(91, 91+27, 55766)-Net in Base 3 — Upper bound on s
There is no (91, 118, 55767)-net in base 3, because
- 1 times m-reduction [i] would yield (91, 117, 55767)-net in base 3, but
- the generalized Rao bound for nets shows that 3m ≥ 66 570149 039528 914751 328661 773851 099671 551356 507215 188567 > 3117 [i]
