is devoted to a branch of mathematics concerned with the fundamental properties, integral definitions, practical applications and graphical representations of multifactorials. These include the well-known factorial function and the less well-known double factorial function.

Web pages are organised into categories and these are presently multifactorials properties, multifactorials applications, functions & formulas, factorial-type functions, graphs & images and people & bios. Resources for corresponding links to categories in other websites include graph theory, number theory and special mathematical functions.

Contributions are invited for individual web pages related to multifactorials. Any potential contribution should be submitted according to an approved format for contributions and will be considered by peer review for inclusion in the website. Preference will be given to material which adds new ideas not already featured elsewhere in, particularly interesting new properties or applications. Selected pages will be published annually in the Journal of Multifactorials & Primes.
