This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories.

Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time.

This category is for Numbers-related articles with topics of unclear notability. See the WikiProject Notability for more information. To add an article to this category, tag it with {{ Notability|type=Numbers}}. (Or if "Numbers" is a standard argument for {{ Notability}} you can use {{ Notability|Numbers}}.)

See the notability guideline for numbers.

• Please improve an article by adding references to reliable sources that verify content within the article, and add extra referenced content if appropriate. Once the article has references to at least two reliable sources that have significant coverage about the subject the Notability tag can be removed.
