TABLE 1.

PTPS first 20 non-trivial normal modes, associated eigenvalues, and level of degeneracy.

Mode 6	0.89	1	0.52
Mode 7	0.92	1	0.50
Mode 8	0.95	2	0.48
Mode 9	0.96	2	0.48
Mode 10	0.96	2	0.48
Mode 11	0.97	1	0.47
Mode 12	1.02	2	0.45
Mode 13	1.03	2	0.44
Mode 14	1.21	1	0.38
Mode 15	1.34	2	0.34
Mode 16	1.35	2	0.34
Mode 17	1.63	1	0.28
Mode 18	1.68	1	0.27
Mode 19	1.79	1	0.26
Mode 20	1.95	2	0.24

The first six trivial modes were excluded, therefore mode 1 represents mode 7.
