Redirect to:

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

To a section: This is a redirect from a topic that does not have its own page to a section of a page on the subject. For redirects to embedded anchors on a page, use {{R to anchor}} 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 Cauchy–Davenport theorem (Q53067086).
- Use this template only on hard redirects – for soft redirects use {{Soft redirect with Wikidata item}}.

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