This category is Wikipedia's subcategory for all categories. All articles, categories and other pages belonging to the encyclopedia are found among the subcategories. It can be good to know that Wikipedia's category structure as a whole is not a "tree": there are many categories that at one level or another have themselves as a subcategory. However, this category is not a subcategory of any other category. The special pages Category Trees and All Categories can be useful for analyzing the structure and structure of the categories. For more information, see the wikipedia page Categories.
