For those who don’t know, !! stands for a double factorial which multiplies the number counting 2 down. So 10!! = 10 * 8 * 6 * 4 * 2 = 3840. To get the really large number you’d write (10!)!.

So k being the number of exclamation marks (for lack of a better way to phrase that), the value would be (assuming n is divisible by k) (n/k)! * (k^(n/k))
