I'm sorry, but "sign factorial notation" is not a commonly used mathematical term or concept.
However, there is a concept called "factorial notation" in mathematics, which is a way of expressing the product of a sequence of consecutive positive integers.
Factorial notation uses the symbol "!" and is defined as follows:
n! = n x (n-1) x (n-2) x ... x 2 x 1
For example, 5! (read as "5 factorial") is equal to:
5! = 5 x 4 x 3 x 2 x 1 = 120
Factorial notation is commonly used in combinatorics and probability theory, where it is used to count the number of possible permutations or combinations of a set of objects.
