# How many identities?

**Algebra**Level 3

Suppose \(S\) is a set with a binary operation. Consider the following sentence about the identity elements in \(S\):

\(S\) has \(\underline{\phantom{1234567}}\) left identities, \(\underline{\phantom{1234567}}\) right identities, and \(\underline{\phantom{1234567}}\) identity elements.

Which choice of words for the blanks gives a sentence that **cannot** be true?
