Magma

 IsRightBol
 test whether a given magma satisfies the right Bol identity

 Calling Sequence IsRightBol( m )

Parameters

 m - Array representing the Cayley table of a finite magma

Description

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

Examples

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

Compatibility

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