return a zero element of a magma with a zero.
Zero( m )
Array representing the Cayley table of a finite magma
The Zero(m) command returns a zero element of a magma m with a zero. If the magma has no zero element, then an exception is raised. In the case in which a magma has multiple zeroes, the first one found is returned.
m ≔ 1|2|3,2|2|2,3|2|1
The Magma[Zero] command was introduced in Maple 15.
