(24, 39, 7659590)-Net in Base 27 — Upper bound on s
There is no (24, 39, 7659591)-net in base 27, because
- 1 times m-reduction [i] would yield (24, 38, 7659591)-net in base 27, but
- the generalized Rao bound for nets shows that 27m ≥ 2 465035 954421 206094 250770 491556 105730 136048 981352 133675 > 2738 [i]
