A comparison has been made between features of low-lying states of a f
our-electron dot and a 2-dimensional four-alpha-particle system. A ser
ies of qualitative features are revealed to be identical. We stress th
e importance of quantum mechanical symmetries iri the understanding of
quantum mechanical few-body systems.
