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.

$\mathrm{with}\left(\mathrm{Magma}\right)\:$

$m≔⟨⟨⟨1\left|1\right|1⟩\,⟨2\left|1\right|2⟩\,⟨3\left|2\right|1⟩⟩⟩$

$m≔\left[\begin{array}{ccc}1& 1& 1\\ 2& 1& 2\\ 3& 2& 1\end{array}\right]$

$\mathrm{IsZeropotent}\left(m\right)$

$\mathrm{true}$

$m≔⟨⟨⟨1\left|2\right|3⟩\,⟨2\left|3\right|3⟩\,⟨3\left|1\right|2⟩⟩⟩$

$m≔\left[\begin{array}{ccc}1& 2& 3\\ 2& 3& 3\\ 3& 1& 2\end{array}\right]$

$\mathrm{IsZeropotent}\left(m\right)$

$\mathrm{false}$

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