Neil Sloane and Simon Plouffe first defined the super form of this expression, which Clifford Pickover used a dollar sign to signify. Sterling's approximation can find large values of these, which are found in the denominator in every term of the Taylor series for ex (e to the x). Used in combinations and permutations, the only prime one of these is 2, and its value for 4 and 5 is 24 and 120, respectively. For 10 points, identify this mathematical expression whose value for n is the product of all positive integers less than or equal to n, symbolized as an exclamation point.
