3. In the (1,1) charge conguration, the rst-excited state involves the promotion of one electron to the higher-energy valley and a complete set of three multiplets [containing an SU(4)-characteristic total of 16 states] are resolved by lifting their degeneracies through the application of a magnetic eld. The related experimental investigation was reported in Ref. . This investigation parallels the recent investigations of the 2e spectra in single bilayer graphene quantum dots . The VFCI results concerning this case are presented in Sec.
