The "rising" type of this function is called the Pochhammer symbol.
The "rising" type of this function is called the Pochhammer symbol. Wilson's theorem states that this function of a prime minus 1 is one less than a multiple of that prime. The approximation "n ln n minus n" for this function's natural logarithm is named for Stirling. The coefficients for the "Taylor series of e to the x" are reciprocals of this function, which is generalized by the gamma function and gives the number of permutations of n when performed on n. For 10 points, the product of the first n numbers gives what function of n denoted by an exclamation point?
