  Using a novel electronic implementation of a well-known time-delayed system,
the Mackey-Glass (MG) system, we investigate the organization of the
trajectories in the phase space, and classify the coexisting solutions, both,
in observations and in model simulations. The numerical simultations are
performed using a discrete-time equation that approximates the exact solutions
of the MG model and in particular, models the delay line in the electronic
circuit. In wide parameter regions, different periodic or aperiodic solutions,
but with similar waveforms exhibiting the alternation of peaks of different
amplitudes, coexist. A symbolic algorithm is proposed to classify those
solutions. The system's phase-space was explored by varying the parameter
values of two families of initial functions.
