    In mathematics, the factorial of a non-negative integer, denoted by ! , is the product of ... [74] and the Boost C++ library. [75] If efficiency is not a concern, ...

  4. Factorial code - Wikipedia

    en.wikipedia.org/wiki/Factorial_code

    If the data are first encoded in a factorial way, however, then the naive Bayes classifier will achieve its optimal performance (compare Schmidhuber et al. 1996). To create factorial codes, Horace Barlow and co-workers suggested to minimize the sum of the bit entropies of the code components of binary codes (1989).

    en.wikipedia.org/wiki/Stirling's_approximation

    [1] [2] [3] One way of stating the approximation involves the logarithm of the factorial: ⁡ (!) = ⁡ + (⁡), where the big O notation means that, for all sufficiently large values of , the difference between ⁡ (!

  7. Falling and rising factorials - Wikipedia

    en.wikipedia.org/wiki/Falling_and_rising_factorials

    In this article, the symbol () is used to represent the falling factorial, and the symbol () is used for the rising factorial. These conventions are used in combinatorics , [ 4 ] although Knuth 's underline and overline notations x n _ {\displaystyle x^{\underline {n}}} and x n ¯ {\displaystyle x^{\overline {n}}} are increasingly popular.

  8. Bhargava factorial - Wikipedia

    en.wikipedia.org/wiki/Bhargava_factorial

    The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n.For example, 5! = 5×4×3×2×1 = 120. By convention, the value of 0! is defined as 1.
