Sexclamation is the largest known factorial number which is the predecessor of a square number: 7! = 5,040 = 5,041-1 = 712-1.

In cultureEdit

Plato mentioned in his Laws that 5,040 is a convenient number to use for dividing many things (including both the citizens and the land of a city-state or polis) into lesser parts, making it an ideal number for the number of citizens (heads of families) making up a polis. He remarks that this number can be divided by all the (natural) numbers from 1 to 12 with the single exception of 11 (however, it is not the smallest number to have this property; 2,520 is).
