Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

From a mathematical expression: This is a redirect from a mathematical symbol or expression to a target article about the symbol or expression.

To an embedded anchor: This is a redirect from a topic that does not have its own page to an embedded anchor on the redirect's target page.
- An {{anchor|(anchor name)}} or {{visible anchor}} template, a HTML element with id="(anchor name)", or an |id=(anchor name) parameter might be installed at the beginning of a paragraph, in or near a section header or within a table. The anchor might also be an old section header that has been edited and is anchored within or near the new header to prevent broken internal and external links.
- Even though section headers of the general form ==(Header name)== are themselves a type of anchor, use {{R to section}} instead.

From a cross-project redirect: This is a redirect from a title associated with an item on Wikidata. The Wikidata item associated with this page is (no entity). Error: no Wikidata item linked! Either link a Wikidata item or remove this template.
- Use this template only on hard redirects – for soft redirects use {{Soft redirect with Wikidata item}}.

With possibilities: This is a redirect from a title that is in draft namespace at Draft:Tau (mathematical constant), so please do not create an article from this redirect (unless moving a ready draft here). You are welcome to improve the draft article while it is being considered for inclusion in article namespace. If the draft link is a redirect, then you may boldly turn that redirect into a draft article. The topic described by this title may be more detailed than is currently provided on the target page or in a section of that page.
- When the target page becomes too large, or for any reason a new page would be an improvement, this redirect may be replaced with an article, template or other project page that is carved out of the target page. See also {{R to section}} and use together with this rcat when appropriate.
- If the topic of the redirect is not susceptible to expansion, then use other rcats such as {{R to section}} or {{R to list entry}} when appropriate.
- Since a new page may be created, links to this redirect should not be replaced with a direct link to the target page. To make redirects to this page, use {{R avoided double redirect}}.
- {{R printworthy}} should be used together with this template when applied to a redirect in mainspace.
- When used on a template redirect, it will automatically populate Category:Template redirects with possibilities.

When appropriate, protection levels are automatically sensed, described and categorized.
