Enter derangement
Calculate !6
Derangements are a permutation where
No original set elements
appear in their same position
Derangements formula for !n:
!n = [n!/e + 0.5]
where [] is the floor function
and e = Eulers constant of 2.718281828459
Plugging in our numbers, we get:
!6 = [6!/2.718281828459 + 0.5]
Calculate 6!
6! = 6 x 5 x 4 x 3 x 2 x 1
6! = 720
!6 = [720/2.718281828459 + 0.5]
!6 = [264.87319764344 + 0.5]
!6 = [265.37319764344]
[265.37319764344] = 265
!6 = 265
