Stability of the Penrose lattice against the other local isomorphism classes isstudied from the viewpoint of electron kinetic energy. Numerical calculations ona tight-binding Hamiltonian with up to 1364 sites indicate that the original Pcnroselattice is the most stable for the electron concentration 0<v<0.082 and0.112<v<0.540. This stability is explained in terms of the ring statistics of the Rattice. Some features of the energy spectrum, energy gaps and degeneracy of the confined/string states, are also discussed.
