5 factorial is just a number .... namely, 120 .
If you want to see all of the 120 'permutations' of five objects, simply do this:
-- List all of the 5-digit numbers from 01,234 to 43,210.
-- Cross off every number on the list that has any digit greater than 4 in it.
-- Cross off every number on the list that has any repeated digit in it.
You'll have all of the 120 permutations of the objects 0, 1, 2, 3, and 4, without repetition.

5 factorial = 5*4*3*2*1 = 120
3!(factorial) or six
you can have 5 24 objects to 120
145 1! = 1 4! = 24 5! = 120
This is just the combination formula (nCr) found in a statistics book: 27!/5!(27-5)! ! stands for factorial . so 27! = 10888869450418352160768000000 and 5!=120 and 22!=1124000727777607680000 ans=80730 note you would hardly ever write the factorial answers out, instead just hit the n! button on your calculator to get a factorial of a number i.e to get 27! just type 27 then n!.
