Webso that a! = a! 1 (the notation was invented just now, and inspired by the n C r -notation for binomial coefficients). Now, apart from the trivial examples ( n!)! ( n!) = n! and a! 1 = a! 2 = a!, when is the generalized factorial a factorial number? When is it the product of two (non-trivial) factorial numbers? As seen above, 10! 8 is both.

WebOther notations for the falling factorial include P(x,n), x P n, P x,n, or x P n. (See permutation and combination.) An alternative notation for the rising factorial x (n) is the less common (x) + n. When (x) + n is used to denote the rising factorial, the notation (x) − n is typically used for the ordinary falling factorial, to avoid confusion.
