mapping class group
Since the set of diffeomorphisms of a manifold which are diffeotopic (http://planetmath.org/Diffeotopy) to the identity is a normal subgroup of the group of all diffeomorphisms, we can form the quotient of the diffeomorphism group by this subgroup. This quotient is known as the mapping class group.
