Ten known states in the heavy nucleus 208Pb at MeV are described by rotating and vibrating tetrahedrons. The
and
yrast states are the first members of the rotational band. A
doublet state with the
yrast state as one member and the newly recognized
yrast state as the other member, the
yrast state, and the third
state are the heads of the three elementary tetrahedral rotating and vibrating bands. The newly recognized state at
keV was assigned spin 2 in 1975 and is suggested to have negative parity by the absent 208Pb
excitation. Four more states at
MeV are identified as the next members of the three elementary tetrahedral rotating and vibrating bands. The ambiguous spin assignment to the state at
keV is settled with
, the state at
keV is assigned
