## Disambiguation

This page lists articles associated with the same title. If an internal link led you here, you may wish to change the link to point directly to the intended article.

**Parity** may refer to:

- Number Theory: The parity of an integer: whether it is even or odd.

- Group Theory: The parity of a permutation of an element of the symmetric group on $n$ letters.

Both concepts have the same origin: **parity** encapsulates the notions of *oddness* and *evenness*.
