 IsZeropotent
 test whether a magma is zeropotent Calling Sequence IsZeropotent( m ) Parameters

 m - Array representing the Cayley table of a finite magma Description

 • A magma is zeropotent if it satisfies the identities (X*X)*Y = (Y*Y)*X = X*X.
 • The IsZeropotent command returns true if the given magma is zeropotent. It returns false otherwise. Examples

 > $\mathrm{with}\left(\mathrm{Magma}\right):$
 > $m≔⟨⟨⟨1|1|1⟩,⟨2|1|2⟩,⟨3|2|1⟩⟩⟩$
 ${m}{≔}\left[\begin{array}{ccc}{1}& {1}& {1}\\ {2}& {1}& {2}\\ {3}& {2}& {1}\end{array}\right]$ (1)
 > $\mathrm{IsZeropotent}\left(m\right)$
 ${\mathrm{true}}$ (2)
 > $m≔⟨⟨⟨1|2|3⟩,⟨2|3|3⟩,⟨3|1|2⟩⟩⟩$
 ${m}{≔}\left[\begin{array}{ccc}{1}& {2}& {3}\\ {2}& {3}& {3}\\ {3}& {1}& {2}\end{array}\right]$ (3)
 > $\mathrm{IsZeropotent}\left(m\right)$
 ${\mathrm{false}}$ (4) Compatibility

 • The Magma[IsZeropotent] command was introduced in Maple 15.
