[Gmsh] Meshing

[josef novak]

Hello,
            I have a problem. I´d like to make easy 3D tetrahedral mesh on the geometry which is in attached file tycka.geo. It should have only 6 elements. This mesh is in attached file tycka.msh. 
        I think, this mesh is not correct. There is 4 tetrahedral elements and 2 elements which are planar - they aren´t tetrahedrons. Could you tell me, how can I make correct mesh? 
                                Thanks
