return a right identity element of a magma with a right identity
RightIdentity( m )
Array representing the Cayley table of a finite magma
The RightIdentity command returns a right identity element of a magma possessing one. If the magma has no right identity element, an exception is raised.
Note that a magma may have more than one right identity; only one right identity is returned.
The Magma[RightIdentity] command was introduced in Maple 15.
For more information on Maple 15 changes, see Updates in Maple 15.
