All ground states and low-lying excitations of a +/- I Ising spin glass model on a cubic 4 x 4 x 4 lattice with periodical boundary conditions were calculated using a method of combinatorical optimization. The structure of states in the phase space is enlightened by a representation by means of clusters in the configuration space and their connectivity. The relaxation behaviour of the system can be described by random walks in the high-dimensional phase space. Rewriting this task as an eigenvalue problem the influence of `entropic barriers' in comparison with an unstructured system can be studied, leading to a better understanding of the anomalous slow dynamic behaviour.
