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
