We analyze the structural stability and symmetry of Ni, Cu, Ag, and Pd metal clusters using the Embedded Atom Method (EAM), developed by Foiles. The structures used in the study are based in polyhedra such as: tetrahedron, hexahedron, triangular antiprism, decahedron, trigonal prism and dodecahedron. To get the various cluster sizes for each one of the polyhedron, top sites over the faces of the polyhedron are placed at the same distance from the face sites. The faces in the polyhedra can be triangular or square faces, f.c.c. clusters are also used. Comparison between the cohesive energy of the various clusters with the same number of atoms but different structured is performed to find out the structural stability, the cluster symmetry is also determined.
