Plato set 5040 as the ideal number of citizens in a city.

What so special about this number?

I think it was because 5040 is divisible by all integers from 1 to 12 (except for 11).  So it is a good number for dividing into smaller groups of equal size.

5040 can also be divided by 144.

5040 is also 7!, but I don't think that was part of the reason.
