[GAP Forum] Error in Function RightTransversal( , )

[Vivek Jain]

  gap> g:=Group((1,2,3,4),(1,2)(3,4));
Group([ (1,2,3,4), (1,2)(3,4) ])
gap> u:=Subgroup(g,[(1,2)(3,4)]);
Group([ (1,2)(3,4) ])
gap> rt:=RightTransversal(g,u);
RightTransversal(Group([ (1,2,3,4), (1,2)(3,4) ]),Group([ (1,2)(3,4) ]))
gap> List(rt);
[ (), (2,4), (1,2,3,4), (1,3)(2,4) ]
   
  In above program rt is not actualy a right transversal
  for (1,2,3,4) and (2,4) are in same right coset.
