GroupOps.Elements( G )
GroupOps.Elements returns the sets of elements of G (see Elements).
The function starts with the trivial subgroup of G, for which the set
of elements is known and constructs the successive closures with the
generators of G using GroupOps.Closure (see Closure).
Note that this function neither checks nor sets the record component
G.elements. It recomputes the set of elements even it is bound to
G.elements.
