The IsRightBol command returns true if the given magma satisfies the right Bol law ((XY)Z)Y = X((YZ)Y).  It returns false otherwise.

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

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

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

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

$\mathrm{true}$

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

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

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

$\mathrm{false}$

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