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 .
