compute the nucleus of a magma
Nucleus( m )
Array representing the Cayley table of a finite magma
The nucleus of a magma is the set of its members that associate with every member of the magma. That is, an element x is in the nucleus if all of the equations (xy)z = x(yz), (yx)z = y(xz) and (yz)x = y(zx) are satisfied, for all y and z from the magma.
The Nucleus command returns the nucleus of the magma m as a set.
The Magma[Nucleus] command was introduced in Maple 15.
