  We study the cluster structure of 20Ne and show that the available
experimental data can be well described by a bi-pyramidal structure with D(3h)
symmetry. Strong evidence for the occurrence of this symmetry comes from the
observation of all nine expected vibrational modes (3 singly degenerate and 3
doubly degenerate) and of six (singly degenerate) double vibrational modes.
20Ne appears to be another example of the simplicity in complexity program, in
which simple spectroscopic features arise out of a complex many-body system.
