Hyperfactorial
Encyclopedia : H : HY : HYP : Hyperfactorial
In mathematics, the hyperfactorial is a function on natural numbers that is related to the factorial. Generally written as H(n), it is defined as
- [H(n)=\prod_^n k^k.]
The hyperfactorial function is similar to the factorial, but produces larger numbers. The rate of growth of this function, however, is not much larger than a regular factorial.
The hyperfactorial function can be generalized to complex numbers in a similar way as the factorial function; the resulting function is called the K-function.
